To calculate a value in Square Kilometers to the corresponding value in Hectares, multiply the quantity in Square Kilometers by 100 (conversion factor).
Hectares = Square Kilometers x 100
The conversion factor from Square Kilometers to Hectares is 100. To find out how many Square Kilometers in Hectares, multiply by the conversion factor or use the Square Kilometers to Hectares converter above.
Square kilometre (International spelling as used by the International Bureau of Weights and Measures) or square kilometer (American spelling), symbol km2, is a multiple of the square metre, the SI unit of area or surface area. 1 km2 is equal to 1,000,000 square metres (m2) or 100 hectares (ha). It is also approximately equal to 0.3861 square miles or 247.1 acres.
The hectare (symbol: ha) is an SI accepted metric system unit of area equal to 100 ares (10,000 m2) and primarily used in the measurement of land as a metric replacement for the imperial acre. An acre is about 0.405 hectare and one hectare contains about 2.47 acres. In 1795, when the metric system was introduced, the "are" was defined as 100 square metres and the hectare ("hecto-" + "are") was thus 100 "ares" or 1⁄100 km2. When the metric system was further rationalised in 1960, resulting in the International System of Units (SI), the are was not included as a recognised unit. The hectare, however, remains as a non-SI unit accepted for use with the SI units, mentioned in Section 4.1 of the SI Brochure as a unit whose use is "expected to continue indefinitely".
