Km2 / Are Units Definition
km2 (Square Kilometer)
The square kilometer (km2) is a unit of measurement of area. One square kilometer is equal to the area of a square whose sides measure one kilometer.
Are
Are, unit of area in the metric system, equal to 100 square meters and the equivalent of 0.0247 acre. Its multiple, the hectare (equal to 100 ares), is the primary unit of land measurement for most of the world. The are was the basic unit of area when the metric system was first decreed in France in 1795. When the International System of Units (SI) was adopted in 1960, the square meter replaced the are as the unit of area, but the International Bureau of Weights and Measures accepted the hectare as the common unit that can be used with the SI.
