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, 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 a summer cottage 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.

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 weave\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

1 m 2	0.0001 ha	0.01 are	1 m 2	10,000 cm2

• 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 measure for the area of ​​land. equal to the area 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

• 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 applied in a number of countries using English system 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

Consider the figure below:

The whole figure consists of 8 squares with a side of 1 cm each.

The area of ​​one such square is called a square centimeter and is written: 1 cm 2.

The area of ​​the whole figure is 8 cm2.

Remember!

Area is measured only V square units length. Always check your answers.

In math to find area geometric shapes use special formulas in which the area is indicated by the capital Latin letter "S".

We remind you that the area of ​​a square can be found by multiplying the length of its side by itself.

The unit of area is the area of ​​a unit square. For example, if the length sides of the square, is equal to 1 m, then its area is equal to 1 square meter (1 m 2); if the length of its side is 1 cm, then its area is 1 square centimeter (1 cm 2).

To find the area of ​​a figure, it is compared with a unit square.

How to convert square units

Consider a square with a side of 1 cm.

Its area is:

S \u003d 1 cm 1 cm \u003d 1 cm 2

Consider a square with a side of 1 m.

Its area is:

S \u003d 1 m 1 m \u003d 1 m 2

It is known that: 1 m = 100 cm

1 m 2 \u003d 1 m 1 m \u003d 100 cm 100 cm \u003d 10,000 cm 2

Let's increase the side of the square equal to 1 m by 10 times. We get a square
side 10 m.

ar or weaving.

S \u003d 10 m 10 m \u003d 100 m 2

In one are - one hundred square meters.

The word "weaving" is often used in summer cottages, although this is the same as "ar".

1 ar (weave) \u003d 100 m 2

To express ar in cm 2, recall that 1 m 2 \u003d 10,000 cm 2.

Means: 1 ar (weaving) \u003d 100 m 2 \u003d 100 10,000 cm 2 \u003d 1,000,000 cm 2

Let's increase the side of the square equal to 10 m by 10 times. We get a square
side 100 m.

The area of ​​such a square is called . Abbreviated "ga". But when pronounced aloud, the name is pronounced completely.

Express hectare in square meters.

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

Now let's determine how many ares are in one hectare.

1 ar \u003d 100 m 2

Means: 10,000 m 2: 100 m 2 \u003d 100 (ar)

1 ha = 100 are

For measuring large areas, for example, territories of states, continents use square kilometer. That is, a square with a side of 1 km and
with an area of ​​1 km 2.

1 km = 1000 m

1 km 2 \u003d 1 km 1 km \u003d 1,000 m 1,000 m \u003d 1,000,000 m 2

For ease of calculation, we offer you a table of conversions of square units to help you.

Square unit conversion table

This table will help convert hectares to sq. meters, hectares to ares and vice versa.

	ha	ar	m 2	cm 2
1 km 2	100 ha	10 000 are	1,000,000 m2	1 000 000 000 cm2

In addition, the prescription for the mandatory use of units SI set out in the current interstate standard in Russia GOST 8.417-2002, which lists the units physical quantities permitted for use, their international and Russian designations are given and the rules for their use are established.

International system of units SI - most used system of units in the world Everyday life as well as in science and technology. Currently SI adopted as the main system of units by most countries of the world and is almost always used in the field of technology, even in those countries in which traditional units are used in everyday life.

SI defines 7 basic units of physical quantities and derived units (abbreviated units SI or units), as well as a set of prefixes.

SI also establishes standard abbreviations for units and rules for writing derived units.

Basic SI units

• kilogram (kg, kg) - unit of mass
• meter (m, m) - unit of length
• second (s, s) - unit of time
• ampere (A, A) - unit of electric current strength
• mole (mol, mol) - unit of the amount of a substance
• candela (cd, cd) - unit of luminous intensity
• kelvin (K, K) is 1/273.16 of the thermodynamic temperature of the triple point of water:
  1. degree Celsius (°C) is a common unit of temperature used in the SI along with the kelvin

Conversion to degrees Celsius:

As part of SI the base units are considered to have independent dimensionality, that is, none of them can be derived from the others.

Derived units are obtained from base units using algebraic operations such as multiplication and division. Some of the derived units in SI assigned their own names, for example, the unit radian.

CI prefixes must be used before unit names. They mean that the unit must be multiplied or divided by a certain integer, which is a power of 10, the number of times.

Decimal prefixes serve to reduce the number of zeros in the numerical values ​​of physical quantities.

For example:

• the prefix "kilo" means multiplying the original unit meter per 1000 (kilometer = 1000 meters)
• the prefix "milli" means multiplying the original unit meter by 10 -3 (millimeter = 0.001 meters)
• the prefix "deci" means multiplication of the original unit meter by 10 -1 (decimeter = 0.1 meters)

Area units

Concerning area units that are derived from the basic unit of length meter, the list looks like this:

• length
  1. unit of measure - meter
  2. designation (Russian) - m
  3. designation (international) - m
• square
  1. unit of measurement - square meter
  2. designation (Russian) - m 2
  3. designation (international) - m 2

Explanation

Meter - the length of the path, traversed by light in vacuum for a time interval
1/299792458 seconds (XVII General Conference on Weights and Measures (CGPM), 1983, Resolution 1).

XXV CGPM, held in 2014, decided to continue work on the preparation of a new revision of the SI, including a redefinition of the meter, and tentatively scheduled to complete this work by 2018 in order to replace the existing SI with an updated version at XXVI CGPM in the same year.

A common system in Russia for measuring land areas (off-system in relation to SI)

• Acre

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

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 October revolution, instead of a tithe.

Old Russian units of area measurement

• 1 sq. verst = 250,000 sq. fathoms \u003d 1.1381 km 2

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 weave.

Here are a few characteristic examples 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, remember a very old joke. “Grandfather asks a fifth grader: “How to find Lenin Square?” And he replies: “You need to multiply the width of Lenin by the length of Lenin” :)))
