Definition of Are
- Definition
-
a — The are is a metric unit of area equal to exactly 100 square meters. It corresponds to the area of a square with sides of 10 meters.
The are was introduced with the metric system in France and is accepted for use with the SI, though it is not an SI unit itself. It is primarily used in land measurement in parts of Europe and in legal or cadastral contexts.
The symbol a is the internationally recognized abbreviation for the are, as documented by the BIPM. Its decimal multiple, the hectare (ha), is far more common in everyday use.
- Exact factor
- 1 a = 100 m²
- Examples
-
- 3 a = 300 m²
- 11 a = 11,840.3 ft²
- 0.93 a = 1,001.04 ft²
Definition of Hectare

ha — The hectare is a metric unit of area equal to exactly 10,000 square meters, or equivalently 100 ares. It represents the area of a square with sides of 100 meters.
The hectare is accepted for use with the International System of Units (SI) and is listed in the BIPM SI Brochure as a non-SI unit whose use is expected to continue indefinitely. It is the primary unit for reporting land area in most countries worldwide.
In agriculture, forestry, urban planning, and environmental science, the hectare serves as the standard measure for expressing the extent of land parcels, forests, and protected areas.
- Exact factor
- 1 ha = 10,000 m²
- Examples
-
- 2.5 ha = 6.1776 ac
- 0.75 ha = 1.8533 ac
- 0.68 ha = 1.6803 ac
About the Hectare
Facts & Uses
- 1 hectare = 10,000 m² = 0.01 km² exactly. The practical metric unit for land and agricultural areas — 100 m × 100 m square.
- Standard for agriculture worldwide outside the US: crop yields (tonnes/ha), farm sizes, vineyards, orchards, ranches.
- Used in forestry (timber harvest tracking), land conservation (protected areas), and European real estate (rural and large estates).
- Reference: a football pitch (FIFA standard) is about 0.7 hectares; a square 100 m on each side = 1 hectare exactly.
Curiosities
- The hectare is not part of the SI, but accepted for use with it — like the liter, it persists because of its convenient scale for everyday land measurement.
- A typical US suburban lot (1/4 acre) is about 0.1 hectare; a French vineyard for fine wine averages 5-15 hectares.
- The EU Common Agricultural Policy (CAP) distributes agricultural subsidies primarily on a per-hectare basis — making it the unit of European farm economics.
- Approximate equivalents: 1 hectare ≈ 2.4711 acres = 10,000 m² = 0.00386 mi².
