## What is are?

The **are** is the original base unit of area in the metric system equal to 100 square meters
(1 a = 100 m2), the standard derived unit of area in the International System of Units (SI). It is also equal to
0.01 hectares (ha) (a unit of area in the metric system), or 0.0001 square kilometers (km2) (a unit of area in
the SI), or 0.0247105381 acres (ac), or 1,076.39104 square feet (sq ft) or 119.599005 square yards (sq yd), which are Imperial / US
customary units of area.

Examples of subdivisions and multiples of the are include:

- The centiare (ca), equal to 0.01 ares (a) or 1.0 square meters (m2)
- The deciare (da), equal to 0.1 ares (a) or 10 square meters (m2)
- The decare (daa), equal to 10 ares (a) or 1,000 square meters (m2)
- The hectare (ha), equal to 100 ares (a) or 10,000 square meters (m2)

One are (a) is equal to one square decametre (dam2) (or square decameter, US spelling), the equivalent unit of area in the International System of Units.
