Convert land area between ares and hectares using their exact decimal relationship. 100 ares = 1 hectare, so the decimal point moves two places in either direction.
An are (a) is exactly 100 square meters. A hectare (ha)is exactly 10,000 square meters. That makes one hectare exactly 100 ares.
Because the relationship is exact, values such as 2.5 ha = 250 aand 37.5 a = 0.375 ha do not require an approximation factor.
This is especially helpful when a parcel plan gives dimensions or area in square meters. For example, 6,500 m² is 65 ares, which is 0.65 hectares.
The two units describe the same quantity, but their scale makes them convenient for different parcel sizes. A smaller lot may be easier to read as 18 aresinstead of 0.18 hectares. A larger holding may be easier to read as 24 hectares instead of2,400 ares.
Unit usage varies by country, land registry, survey document, and property market. For legal or cadastral work, keep the authoritative unit and precision shown in the governing record; use this converter for the equivalent value.
Suppose a land record lists a parcel as 2,500 ares. Divide by 100 to express the same area in hectares.
The same parcel is therefore exactly 25 hectaresor 250,000 square meters.
Exactly 100 ares. Since 1 are = 100 m² and 1 hectare = 10,000 m², the ratio is exactly 100:1.
Exactly 0.01 hectare. Divide any value in ares by 100.
Yes. For example, 2.5 ares = 0.025 hectares, and 0.375 hectares = 37.5 ares.
The hectare is a metric, non-SI unit defined as 10,000 m². It is widely used for land area. Square meter (m²) is the SI derived unit of area.
Yes. One are is exactly 100 m², equivalent to the area of a 10 m × 10 m square.
Use the authoritative unit and precision required by the relevant registry, survey, contract, or jurisdiction. A converted value is useful for comparison, but it should not replace the governing record.
