What is a Hectare?
The hectare (symbol: ha) is a metric unit of area defined as 10,000 square meters. It is equivalent to a square with 100-meter sides. While the square meter is the primary SI unit of area, the hectare is widely used in agriculture, forestry, and land management for measuring large tracts of land.
Our hectare conversion tool helps you easily convert between hectares and other units. For example, 1 hectare is approximately 2.471 acres.
Is Hectare an SI Unit?
The hectare is not an official SI unit, but it is a non-SI unit that is accepted for use with the International System of Units (SI). The official SI unit for area is the square meter (m²). The relationship is straightforward:
- 1 hectare (ha) = 10,000 square meters (m²)
- 1 hectare (ha) = 100 ares
- 1 square kilometer (km²) = 100 hectares (ha)
What are Hectares Used For?
Hectares are primarily used for measuring large areas of land, making them a standard unit in several fields:
Agriculture & Farming
Farmers use hectares to measure field sizes for planting crops, calculating yields, and managing livestock grazing areas.
Forestry & Conservation
Used to measure forest size, plan reforestation projects, and manage national parks and conservation areas.
Urban Planning & Real Estate
City planners and developers use hectares to measure land parcels for new housing developments, parks, and industrial zones.
Land Sales & Registration
In most countries using the metric system, land ownership and deeds are officially registered in hectares.
Etymology and History
The term "hectare" was first introduced in France in 1795. It combines the Greek prefix "hecto-", meaning "hundred," with the metric area unit "are." The "are" itself is based on the meter, representing an area of 100 square meters (10m x 10m). Therefore, a "hect-are" is 100 ares, or 10,000 square meters.
This system was created during the French Revolution as part of the new metric system, designed to be logical and standardized. The hectare quickly became a practical unit for land measurement, replacing many traditional and often inconsistent local units across Europe and the world.
Frequently Asked Questions
Why is the hectare used for land measurement?
The hectare provides a convenient scale for measuring land. A square meter is too small for large fields, and a square kilometer is too large for most farms. The hectare (about the size of two football fields) offers a practical, human-scale unit for agriculture, forestry, and planning.
How big is a hectare visually?
A hectare is equivalent to 10,000 square meters. A common way to visualize it is as the area of a square with sides of 100 meters. It's also roughly the size of an international rugby union field or 2.47 acres.
What's the difference between a hectare and an acre?
Both are units of land area. A hectare is a metric unit (10,000 m²), while an acre is an imperial unit (4,840 square yards). A hectare is larger than an acre: 1 hectare ≈ 2.471 acres.
How do I convert hectares to other units?
Use our hectare conversion calculators above or multiply by the correct conversion factor. For example, to convert hectares to square meters, multiply by 10,000. To convert hectares to acres, multiply by 2.471. Our tool simplifies these conversions for you.
Is the hectare an official SI unit?
No, the hectare is not an SI unit, but it is a "non-SI unit accepted for use with the SI." The official SI unit of area is the square meter (m²). The hectare is used because of its practical convenience in land measurement.
