How to Convert a Hectare to Other Units
Here’s how to convert a hectare to other popular units of measurement:
A hectare is equal to 10,000 square meters and 2.471 acres in the British Imperial System. To convert hectares to square meters, multiply the value of hectares by 10,000.
Square meters = hectares x 10,000
A hectare is equal to 0.01 square kilometers. To convert hectares to square kilometers, divide the value of hectares by 100.
Square kilometers = hectares ÷ 100
There are approximately 107,639 square feet in one hectare. To convert hectares to square feet, multiply the value of hectares by 107,639.
Square feet = hectares x 107,639
One hectare contains 0.00386102 square miles. To convert hectares to square miles, divide the hectare value by 259.
Square miles = hectares ÷ 259
What is a Hectare?
A hectare is a unit of measurement for assessing the size of land. The symbol for hectare is ha, and it’s a unit of the metric system. The hectare is an accepted measurement in countries that use the metric system.
The metric system originated around 1795 when the measurement “are” was introduced. An are is equal to one square decametre or one hundred square meters. A hectare is the equivalent of 100 ares. Because it’s so much larger than are, the hectare became standard for land measurement.
In 1960, members of the 11th General Conference on Weights and Measurements created the International Systems of Units (SI) to establish a consistency of measurements from country to country.
In this development, the “are” was left out of the metric system or SI. But, hectare remained a recognized measurement. Here’s a breakdown of how a hectare compares to other common measurements:
- A hectare is equivalent to 2.471 acres
- One hectare is equal to 107,639 sq ft
- A hectare is the same as 10,000 sq km
What is an Acre?
An acre is a form of land measurement used in the United States, the United Kingdom, the US Virgin Islands, some parts of South Asia, and a few other countries. An acre is a measurement from the Imperial System and US Customary Units.
The original measure of an acre had the definition of “one chain by one furlong” or 66 feet x 660 feet. Here’s a breakdown of an acre compared to other common measurements:
- 1 acre is equivalent to 0.4047 hectares
- One acre equals 43,560 square feet
- An acre is the same as 4,047 square meters
