Hectare

A hectare (symbol ha) is a metric unit of surface area, equal to 100 ares (the name is a contraction of the SI prefix hecto + are). It is a non-SI unit currently accepted (although discouraged) for use with the SI. In India, also the abbreviation hac is used. One hectare is equivalent to:

• 100 ares
• 10 000 square metres
• 1 square hectometre (a square with sides 100 metres long)
• 0.01 square kilometres
• 2.471 053 8 international acres
• 2.471 043 9 U.S. survey acres

Conversely:

• 100 hectares is equal to one square kilometre
• 0.404 685 64 hectares is equal to one international acre
• 0.404 687 26 hectares is equal to one U.S. survey acre
