Enter the quantity you are interested in in the left field square meters, which you want to convert. In the field on the right you will see the result of the calculation. If you need to convert square meters or hectares to other units, just click on the appropriate link.

Square meter (m², m²) is a unit of area measurement adopted in the SI, MTS and MKGSS systems. One square meter is equal to the area of ​​a square with a side of 1 m. There are 10,000 square centimeters in one square meter.

What is "hectare"

Hectare (ha, ha) is an off-system unit of area measurement. One hectare is equal to the area of ​​a square with sides of 100 m. This unit is accepted International Committee weights and measures in 1879, currently used in conjunction with SI units. On the territory of the Russian Federation in hectares measure the area in the forest and agriculture. Along with hectares, measurements are carried out in hundredths, equal to one hundredth of a ha (100 sq. M).

The concept of "hectare" was put into practice after 1917 and replaced the tithe - 1 ha was equal to 11-12 tithes. Since the 1930s, the abbreviated version "ha" has entered everyday speech. To visualize an area of ​​one hectare, imagine a rugby field (1.008 hectares) or a football field (0.714 hectares).

1 acre = 4840 square yards = 4046.86 m 2

The most commonly used land measure in practice is hectare - the abbreviation ha:

1 ha = 100 are = 10,000 m 2

In Russia, a hectare is the main unit for measuring land area, especially agricultural land.

On the territory of Russia, the unit "hectare" was put into practice after the October Revolution, instead of the tithe.

Old Russian units of area measurement

• 1 sq. verst = 250,000 sq. fathoms = 1.1381 km²
• 1 tithe = 2400 sq. fathoms = 10,925.4 m² = 1.0925 ha

• 1 octopus \u003d 1/8 tithe \u003d 300 square sazhens \u003d 1365.675 m² ≈ 0.137 ha.

The area of ​​land plots for individual housing construction, private household plots is usually indicated in acres

One hundred- this is the area of ​​\u200b\u200ba plot measuring 10 x 10 meters, which is 100 square meters, and therefore is called a hundred.

Here are some typical examples of the sizes that a land plot of 15 acres can have:

In the future, if you suddenly forget how to find the area of ​​a rectangular plot of land, then remember a very old joke when a grandfather asks a fifth grader how to find Lenin Square, and he answers: “You need to multiply the width of Lenin by the length of Lenin")))

It is useful to know this

• For those who are interested in the possibility of increasing the area of ​​land plots for individual housing construction, private household plots, gardening, horticulture, which are owned, it is useful to familiarize yourself with the procedure for registration of cuttings.

• From January 1, 2018, the exact boundaries of the site must be recorded in the cadastral passport, since it will simply be impossible to buy, sell, mortgage or donate land without an accurate description of the boundaries. This is regulated by amendments to the Land Code. A total revision of the borders at the initiative of the municipalities began on June 1, 2015.

• On March 1, 2015, a new the federal law“On Amendments to the Land Code of the Russian Federation and Certain Legislative Acts of the Russian Federation” (N 171-FZ “dated 06/23/2014), in accordance with which, in particular, the procedure for purchasing land plots from municipalities has been simplified&You can read the main provisions of the law here.

• With regard to the registration of houses, baths, garages and other buildings on land owned by citizens, the situation will improve with a new dacha amnesty.

How many square meters in a hectare?

How many acres in 1 hectare

Excavation

21.10.2013 35695

Despite the fact that we often see the concepts of “hundred”, “hectare”, “square meter” in various sources, many people have difficulty when it comes to converting one of the measures of area measurement to another. In fact, there is nothing complicated in this process.

Units of land area measurement

All three concepts denote a measure of area.

It is very easy to remember how many acres are in 1 hectare and how many square meters. The title itself already contains a clue.

Just remember the ratios:

1 ha = 100 acres,

1 weave = 100 square meters (m2),

1 ha = 10,000 square meters.

As you can see, everything is very simple, it is enough to know this simple formula and be able to apply it.

For example, there is a plot of 20 hectares. In order to find out how many acres are in it, we multiply 20 (the total number of hectares) by 100. We get the following equation:

That is, twenty hectares contain 20 acres.

In the same way, weaving can be converted to hectares. Let's say we know that this area has 300 acres, and we need to measure it in hectares. Again, we recall how many acres are in 1 hectare, and we get:

That is, our plot of three hundred acres contains only three hectares.

Similarly, you should act if you need to convert square meters to hundredths or hectares and vice versa.

Let's take our plot of 20 hectares. We know that one hectare contains 10 thousand square meters. Therefore, the conversion to square meters will look like this:

20x10000 = 200000, that is, in 20 thousand hectares - two hundred thousand square meters.

Now let's calculate how many square meters are in 10 acres. As we remember, 1 weave is one hundred square meters, therefore, we get the following calculation:

10x100=1000 sq.m.

Despite the fact that all of these quantities are a measure of the area, they are used in different cases.

In square meters, the area of ​​\u200b\u200bhousing is most often measured, as well as small plots, the size of which is less than 10 meters in length and 10 in width.

In this way, small building plots or country plots can be measured. The size of the land area, which is usually measured in acres, does not exceed 100 meters in length and a hundred in width. Larger plots (one measurement over 100 meters) are already measured in hectares. And if one of the dimensions of the site is more than a thousand meters, then it can be measured already in square kilometers. So it's not so difficult to calculate it all on your own, knowing a simple formula.

Quick answer: There are 10,000 square meters in one hectare.

A hectare (ha) is a metric unit of area (it common name international decimal system units, which is based on the use of kilogram and metre), equal to the area a square with a side of 100 meters. In total we have: 1 ha = 10,000 m2 = 100 ar = 100 acres.

How much per hectare

In our country, a hectare is considered the main unit for measuring land area, in particular, agricultural. We also often use another unit of area - weaving, which is equivalent to one hundredth of a hectare. Interestingly, until 1917, another value was used on the territory of our country, called a tithe: it is believed that it arose before the 15th century and was equal to 2400 square sazhens. It was a rectangle with sides of 60 by 40 fathoms or 80 by 30. As for the hectare, this unit began to be used immediately after the October Revolution and the ratio 1 ha = 11/12 tithes was used for translation. The abbreviation "ha" began to be used around the 30s.

By the way, why do we need this unit? Let's say you want to buy a plot for the construction of a summer house or a capital house. The ads usually indicate hundreds, but often hectares. It is clear that 1 hectare is a huge amount of land on which you can safely build several tens or even hundreds of houses. True, the cost of 1 hectare of land is certainly an absolutely exorbitant amount. In addition, hectares are usually sold not for development, but for planting crops.

Irina, p. Urusovo, Lipetsk Region We want to put greenhouses, we need to make calculations. Tell me, how many acres and square meters in 1 ha?
If you indicate the area of ​​the field with a side of several kilometers, then the recording of the site measurements will be very multi-digit and difficult to sound. Therefore, to measure and record very large areas, it is more convenient to use such units as weave and hectare. Let's try to calculate how many square meters are contained in a hectare and how many acres is 1 ha.

Square meter

The square meter is a unit of area measurement. Visually, you need to draw a square with a side of 1 m. The area of ​​\u200b\u200bthe square is 1 square meter (we consider 1 x 1 \u003d 1), hence the name.

Weaving

Weave is also a unit of area measurement. We present a square with a side equal to 10 m. The area of ​​\u200b\u200bweaving is 100 square meters (we consider 10 x 10 \u003d 100). Easy to remember: weaving - one hundred square meters.

Hectare

Hectare is the most popular unit of measure in the agricultural sector. To calculate the area of ​​a hectare, a square with a side equal to 100 m is visually drawn. The area of ​​​​a hectare is 10,000 square meters (100 x 100 \u003d 10,000).
Thus, we get a visual comparison of units.

What is weaving, ar, hectare, square kilometer? How many hectares, square meters and kilometers in one are (hundred) of land? How many square meters, kilometers and acres are in one hectare of land? How many acres, hectares and square meters in one square kilometer?

How many square meters in 1, 10, 100, 1000 acres: table

What is an acre of land? Weave of land is a unit of measurement of the size of the site, weaving is equal to one hundred square meters.

The following units are used to measure areas: square millimeter (mm 2), square centimeter(cm 2), square decimeter (dm 2), square meter (m 2) and square kilometer (km 2).
For example, a square meter is the area of ​​a square with a side of 1 m, and a square millimeter is the area of ​​a square with a side of 1 mm.

You can also say that in one weave of 100 square meters. meters and it will be correct if we say in hectares that one weave is one hundredth of a hectare.

• Weaving is a unit of measurement for the size of a plot, which is often used in summer cottages or agriculture. In science, it is customary to use an analogue of weaving - ar. Ar (weaving) - the area of ​​​​a square with a side of 10 m.
• Based on the name of this measure, you can already guess that we are talking about hundreds of meters.
• Indeed, one weave is equal to 100 m 2.
• In other words, one weave will be equal to the area of ​​​​a square with sides of 10 m.
• Accordingly, in ten acres there will be 1000 m 2.
• 100 acres contain 10,000 m 2, and 1000 acres contain 100,000 m 2.
• In other words, to calculate how many square meters are in a given number of acres, you need to multiply the acres by 100.

Area units

1 weave = 100 square meters = 0.01 hectare = 0.02471 acre

• 1 cm 2 \u003d 100 mm 2 \u003d 0.01 dm 2

Area units conversion table

The system adopted in Russia for measuring land areas

• 1 weave = 10 meters x 10 meters = 100 sq.m
• 1 hectare \u003d 1 ha \u003d 100 meters x 100 meters \u003d 10,000 square meters \u003d 100 acres
• 1 square kilometer = 1 sq. km = 1000 meters x 1000 meters = 1 million sq. m = 100 hectares = 10,000 acres

Inverse units

• 1 sq. m = 0.01 acres = 0.0001 ha = 0.000001 sq. km
• 1 weave \u003d 0.01 ha \u003d 0.0001 sq. km

• To calculate how many acres are in square meters, you need to divide the given number of square meters by 100.
• Thus, in 1 m 2 there are 0.01 weave, in 10 m 2 - 0.1 weave, and in 100 m 2 - 1 weave.

What is a hectare of land?

Hectare- a unit of area in the metric system of measures used to measure land. Field areas are measured in hectares (ha). A hectare is the area of ​​a square with a side of 100 m. So, 1 ha is equal to 100,100 square meters, that is, 1 ha = 10,000 m 2.

Abbreviated designation: Russian ha, international ha. The name "hectares" is formed by adding the prefix "hecto..." to the name of the area unit "ar"

1 ha \u003d 100 ar \u003d 100 m x 100 m \u003d 10,000 m 2

• A hectare is a unit of measurement for the size of a plot, which is equal to the area of ​​a square with sides of 100 m. A hectare, like a weave, is mainly used as measuring units only in agriculture and summer cottages.
• The designation of a hectare looks like "ha".
• One hectare is equal to 10,000 m 2 or 100 acres.

How many square meters in 1, 10, 100, 1000 hectares: table

• In order to calculate how many square meters in a given number of hectares, you need to multiply the number of hectares by 10,000.
• Thus, there are 10,000 m 2 in 1 ha, 100,000 m 2 in 10 ha, 1,000,000 m 2 in 100 ha, and 1,000,000 m 2 in 1000 ha.

Thus, one hectare corresponds to 10,000 m2. It can easily fit a football field (0.714 hectares) or more than 16 summer cottages (the area of ​​​​each is 6 acres). Well, Red Square will be twice as large as one hectare, its area is 24,750 m 2.

1 square kilometer is 100 times larger than 1 hectare. Similarly, we determine: 1 ha - how many acres are in the composition. One weave covers an area of ​​100 square meters. Therefore, in comparison with a hectare, weaving is 100 times less than a hectare.

• 1 weaving\u003d 10 x 10 meters \u003d 100 m 2 \u003d 0.01 ha
• 1 hectare (1 ha)\u003d 100 x 100 meters or 10,000 m 2 or 100 acres
• 1 square kilometer (1 km2)\u003d 1000 x 1000 meters or 1 million m 2 or 100 hectares or 10,000 acres
• 1 square meter (1 m 2)= 0.01 acres = 0.0001 ha

How many acres in 1, 10, 100, 1000 ha: table

• To calculate how many acres corresponds to a given number of hectares, you need to multiply the number of hectares by 100.
• So, in 1 hectare there are 100 acres, in 10 hectares - 1000 acres, in 100 hectares - 10,000 acres, and in 1000 hectares - 100,000 acres.

How many hectares in 1, 10, 100, 1000, 10,000 acres, square meters: table

• To calculate how many hectares are contained in a given number of acres, you need to divide the number of acres by 100.
• And in order to carry out such calculations with square meters, it is necessary to divide their number by 10,000.
• So, in 1 acres there are 0.01 ha, in 10 acres - 0.1 ha, in 100 acres - 1 ha, in 1000 acres - 10 hectares, in 10,000 acres - 100 hectares.
• In turn, in 1 m 2 there are 0.0001 ha, in 10 m 2 - 0.001 ha, in 100 m 2 - 0.01 ha, in 1000 m 2 - 0.1 ha, and in 10000 m 2 - 1 ha.

How many square kilometers are in 1 hectare?

1 ha \u003d 10,000 m 2

1 km 2 \u003d 100 ha

• A square kilometer is a unit of land area measurement, equal to the area of ​​a square with sides of 1000 meters.
• There are 100 hectares in one square kilometer.
• Thus, to calculate the number of square kilometers in a hectare, it is necessary to divide its given number by 100.
• So, in 1 ha there are 0.01 km 2

What is 1 are equal to?

Ar a unit of area in the metric system of measures, equal to the area of ​​​​a square with a side of 10 m

• 1 ar \u003d 10 m x 10 m \u003d 100 m 2 .
• 1 tithe = 1.09254 ha.

• Arom is a unit of measure for the size of a plot, equal to the area of ​​a square with sides of 10 m.
• In other words, ar is equal to a hundredth.
• In 1 are there are 100 m 2, 1 weave, 0.01 ha, 0.0001 km 2.

How many ares are in one hectare?

• There are 100 ares in one hectare, just like acres.

What is 1 acre equal to?

Acre land measure used in a number of countries using the English system of measures (Great Britain, USA, Canada, Australia, etc.).

1 acre \u003d 4840 sq. yards \u003d 4046.86 m 2

Old Russian units of area measurement

• 1 sq. verst = 250,000 sq. fathoms = 1.1381 km²
• 1 tithe = 2400 sq. fathoms = 10,925.4 m² = 1.0925 ha

About, how many acres in one hectare and how to calculate all this correctly, you will learn by reading the following material in the article. Collected quality information.

I think any person at least once in his life will have or hectares. Then it will be useful for you to find out how many acres are in one hectare and how to calculate everything correctly.

The ability to convert hundreds to hectares or vice versa will be useful in different areas activities: in construction, agricultural work, buying and selling land.

How is one hectare calculated

The most common unit of measurement for the area of ​​agricultural land is the hectare. Visually, it can be represented as a square of 100 by 100 meters.

This unit of measurement usually shows the areas of large farms, parks, nature reserves, etc.

The area of ​​a hectare can be determined using simple mathematical operations.

S \u003d 100 * 100 \u003d 10,000 m 2

That is, one hectare 10 thousand square meters.

It should not be confused with the square kilometer, which is also used to measure fairly large areas. One square kilometer is also a square, but with sides of 1000 meters.

It is generally accepted that if the land has sides whose length is within from 100 to 1000 m, then the hectare is taken as the unit of measurement.

How to measure the area of ​​an irregularly shaped plot

It is not always necessary for us to measure and translate the area of ​​the land correct form what to do if you have to work with trapezoidal or round territories.

If the land plot has a round shape, then apply the formula for calculating the area of ​​​​a circle, this is S \u003d n r 2, where n is the number Pi (3.14), and r is the radius.

In the event that the site is uneven, or it is too difficult to visually divide it into simpler figures, then you should contact specialists who, using the necessary equipment and instruments, will provide you with accurate information about the area and then it will be possible to convert it into the desired units.

It is worth considering that experts calculate the area in square meters and round it up to 1 m 2.

First, you need to explain what a cell is. One acre is a plot, the size one hundred one hundred. That is, its area is 100 m 2. Weaves are used if you need to measure a relatively small area, for example, for a summer cottage or a garden.

By the ratio of the areas of one hectare and one weave, you can find out the answer to the question posed at the beginning of the article.

10,000 m 2 / 100 m 2 \u003d 100

That is, in one hectare can be "put in" 100 acres.

How to convert hundreds to hectares

It is quite easy to do this. This is where some basic math comes in handy. In order to convert acres to hectares, you need to add the proportion. For example, you need to convert 27 acres to hectares (hectares).

We already know that in one hectare there are 100 acres, and, for example, in X(x) hectares - 27 acres. Then the proportion looks like this:

Respectively, X= 1*27/100. Eventually, X equals 0.27 hectares. This will be the area of ​​the plot, presented in hectares.

If you are afraid of making a mistake, then you can use special online convectors that will convert acres to hectares in a few seconds, or vice versa.

More about the square

General information

Area is the size geometric figure in two-dimensional space. It is used in mathematics, medicine, engineering, and other sciences, such as calculating the cross section of cells, atoms, or pipes such as blood vessels or water pipes. In geography, area is used to compare the sizes of cities, lakes, countries, and other geographic features. Area is also used in population density calculations. Population density is defined as the number of people per unit area.

Units

Square meters

Area is measured in SI units in square meters. One square meter is the area of ​​a square with a side of one meter.

unit square

A unit square is a square with sides of one unit. The area of ​​a unit square is also equal to unity. In a rectangular coordinate system, this square is at coordinates (0,0), (0,1), (1,0) and (1,1). On the complex plane, the coordinates are 0, 1, i and i+1, where i is an imaginary number.

Ar

Ar or sotka, as a measure of area, is used in the CIS countries, Indonesia and some other European countries, to measure small urban objects such as parks, when a hectare is too large. One are is equal to 100 square meters. In some countries, this unit is called differently.

Hectare

Real estate is measured in hectares, especially land plots. One hectare is equal to 10,000 square meters. It has been in use since the French Revolution, and is applied in European Union and some other regions. As well as ar, in some countries the hectare is called differently.

Acre

AT North America and Burma area is measured in acres. Hectares are not used there. One acre is equal to 4046.86 square meters. Initially, an acre was defined as the area that a peasant with a team of two oxen could plow in one day.

barn

Barns are used in nuclear physics to measure the cross section of atoms. One barn equals 10⁻²⁸ square meters. Barn is not a unit in the SI system, but is accepted for use in this system. One barn is approximately equal to the cross-sectional area of ​​the uranium nucleus, which physicists jokingly called "huge as a barn." Barn in English "barn" (pronounced barn) and from a joke of physicists, this word became the name of a unit of area. This unit originated during World War II, and scientists liked it because its name could be used as a code in correspondence and telephone conversations within the Manhattan Project.

Area calculation

The area of ​​the simplest geometric figures is found by comparing them with the square of a known area. This is convenient because the area of ​​a square is easy to calculate. Some formulas for calculating the area of ​​​​geometric shapes below are obtained in this way. Also, to calculate the area, especially a polygon, the figure is divided into triangles, the area of ​​\u200b\u200beach triangle is calculated using the formula, and then added. The area of ​​more complex figures is calculated using mathematical analysis.

Area formulas

• Square: square side.
• Rectangle: product of the parties.
• Triangle (side and height are known): the product of a side and the height (the distance from that side to the edge) divided in half. Formula: A = ½ah, where A- square, a- side, and h- height.
• Triangle (two sides and the angle between them are known): the product of the sides and the sine of the angle between them, divided in half. Formula: A = ½ab sin(α), where A- square, a and b are the sides, and α is the angle between them.
• Equilateral triangle: side, squared, divided by 4 times Square root out of three.
• Parallelogram: the product of a side and the height measured from that side to the opposite side.
• Trapeze: the sum of two parallel sides multiplied by the height, divided by two. Height is measured between these two sides.
• A circle: the product of the square of the radius and π.
• Ellipse: product of semiaxes and π.

You can find the surface area of ​​simple three-dimensional figures, such as prisms, by unfolding this figure on a plane. It is impossible to obtain a ball scan in this way. The surface area of ​​a sphere is found using the formula by multiplying the square of the radius by 4π. From this formula it follows that the area of ​​a circle is four times less than the surface area of ​​a ball with the same radius.

Surface areas of some astronomical objects: Sun - 6.088 x 10¹² square kilometers; Earth - 5.1 x 10⁸; thus, the surface area of ​​the Earth is about 12 times smaller than the surface area of ​​the Sun. The surface area of ​​the Moon is approximately 3.793 x 10⁷ square kilometers, which is about 13 times smaller than the surface area of ​​the Earth.

planimeter

The area can also be calculated using a special device - a planimeter. There are several types of this device, for example, polar and linear. Also, planimeters are analog and digital. In addition to other features, digital planimeters can be scaled to make it easier to measure features on a map. The planimeter measures the distance traveled along the perimeter of the measured object, as well as the direction. The distance traveled by the planimeter parallel to its axis is not measured. These devices are used in medicine, biology, engineering, and agriculture.

Area properties theorem

According to the isoperimetric theorem, of all figures with the same perimeter, the most big square at the circle. If, on the contrary, we compare figures with the same area, then the circle has the smallest perimeter. The perimeter is the sum of the lengths of the sides of a geometric figure, or a line that marks the boundaries of this figure.
