1 hectare = 10,000 square metres
What is hectare?
A hectare is a metric unit of area equal to 10,000 square metres. It is the standard unit for measuring agricultural land, forest areas, and large parcels of real estate in metric countries.
Notes: Land area unit
Real-world uses
Hectares are the standard unit for agricultural land measurement, forestry management, and urban planning worldwide. Wine regions report vineyard sizes in hectares, and environmental reports quantify habitat loss in hectares. One hectare is roughly the size of two American football fields.
History
The hectare was introduced during the French Revolution as part of the metric system, originally called a "hecto-are" (100 ares). Though not an official SI unit, it is accepted for use with SI and remains the predominant land area unit in global agriculture.
Common mistakes
Confusing hectares with acres—1 hectare is about 2.47 acres, not 1-to-1. Also, some people confuse "hectare" with "hectometre," but a hectare is 10,000 m² (100 m × 100 m), a unit of area, not length.
When is this conversion used?
Converting hectare to square metre is useful in the area domain when comparing values across different measurement standards or applying formulas that require a specific unit.
How to convert hectare to square metre
To convert hectare to square metre, multiply the value by 10,000.

Measurement standards
The square metre is the SI derived unit of area. The hectare (10,000 m²) is accepted for use with the SI by the BIPM, particularly for land measurement, though it is not an SI unit itself.

Vatican City, the world's smallest independent state, covers just 0.44 km² (about 109 acres) — smaller than many golf courses. By contrast, Russia spans over 17.1 million km², nearly 39 million times larger.
