Area Unit Converter

Area Unit Converter allows you to make simple and accurate conversions between various units of area, metric and non-metric: square meters to square foot, yard, inch, mile, acre, are, hectare, and others.

Convert between area units

Every unit of length has a corresponding unit of area, namely the area of a square with the given side length. Thus areas can be measured in square meters (m²), square centimeters (cm²), square millimeters (mm²), square kilometers (km²), square feet (ft²), square yards (yd²), square miles (mi²), and so forth. Algebraically, these units can be thought of as the squares of the corresponding length units.

Conversions

Calculation of the area of a square whose length and width are 1 meter would be:

1 metre x 1 metre = 1 m²

and therefore, another square with different sides can be calculated as:

3 metres x 2 metres = 6 m². This is, however, equivalent to 6 million millimeters square. Following this,

• 1 kilometre square = 1,000,000 metres square
• 1 metre square= 10,000 centimetres square = 1,000,000 millimetres square
• 1 centimetre square = 100 millimetres square

Non-Metric units

In non-metric units, the conversion between two square units is the square of the conversion between the corresponding length units.

1 foot = 12 inches,

the relationship between square feet and square inches is

1 square foot = 144 square inches,

where 144 = 122 = 12 × 12. Similarly:

• 1 square yard = 9 square feet
• 1 square mile = 3,097,600 square yards = 27,878,400 square feet

In addition, conversion factors include:

• 1 square inch = 6.4516 square centimetres
• 1 square foot = 0.09290304 square metres
• 1 square yard = 0.83612736 square metres
• 1 square mile = 2.589988110336 square kilometres

Other Units Including Historical

There are several other common units for area. The "Are" was the original unit of area in the metric system, with;

1 are = 100 square meters

Though the are has fallen out of use, the hectare is still commonly used to measure land:

1 hectare = 100 ares = 10,000 square metres = 0.01 square kilometres

Other uncommon metric units of area include the tetrad, the hectad, and the myriad.

The acre is also commonly used to measure land areas, where

1 acre = 4,840 square yards = 43,560 square feet.

An acre is approximately 40% of a hectare.

On the atomic scale, area is measured in units of barns, such that:

1 barn = 10−28 square meters.

The barn is commonly used in describing the cross-sectional area of interaction in nuclear physics.

In India,

• 20 Dhurki = 1 Dhur
• 20 Dhur = 1 Khatha
• 20 Khata = 1 Bigha
• 32 Khata = 1 Acre
