What Is Hectare (ha)?
A hectare is a unit used to measure the size of land. It is often used for farms, forests, parks and large pieces of land. One hectare is a square piece of land that is 100 meters long and 100 meters wide.
Definition
A hectare is a metric unit of area. It is exactly equal to 10,000 square meters. You can imagine it as a big square field. Each side of the square is 100 meters. So 100 meters times 100 meters makes 10,000 square meters. That whole square is one hectare.
In simple words, a hectare tells you how large a piece of ground is. It is much bigger than a house lot and is useful when talking about farms or whole pieces of land.
History / Origin
The hectare comes from the metric system, which started in France in the late 1700s. People wanted a simple way to measure length, weight and area using powers of ten. The word hectare is made from two parts. The first part hecto means one hundred. The second part are is an old metric unit of area that means 100 square meters.
One are is 10 meters by 10 meters. Since a hectare is 100 ares, it became 100 times bigger than an are. That equals 10,000 square meters. Over time, many countries that use the metric system also started using the hectare to measure land, especially for farming and planning land use.

Current Use Around the World
The hectare is widely used in many countries that follow the metric system. It is very common in Europe, Asia, Africa, South America and many other parts of the world. It is one of the main units for:
- Farming and agriculture, to describe the size of fields and farms
- Forestry, to measure areas of forest and woodland
- City and land planning, to plan housing, roads and parks
