History and Origin of the Hectare

The hectare was born of the metric system in 1795, during the French Revolution. Its name joins the prefix hecto- (one hundred) with the are — a unit of exactly 100 square meters. One hundred ares therefore make one hectare, and a single square meter is also called a centiare. Because every step is a power of ten, the whole family locks together with no rounding:

Quick Tips & Mental Math

To turn hectares into square meters, just add four zeros — or shift the decimal point four places to the right: 1 ha → 10,000 m², 2.5 ha → 25,000 m². For fractions of a hectare, scale from 10,000: 0.5 ha is half of that (5,000 m²), and 0.1 ha is a tenth (1,000 m²).
