How to Convert Hectares to Acres
The hectare (ha) is the standard metric unit of land area, defined as 10,000 square meters. The acre (ac) is the customary unit used in the US, UK, Canada, Australia, and South Asia.

Or divide hectares by 0.40468564224.
Worked Examples:
- Example 1: Convert 2 Hectares to Acres:
2 × 2.471054 = 4.94211 ac (Just under 5 acres). - Example 2: Convert 5 Hectares to Acres:
5 × 2.471054 = 12.35527 ac. - Example 3: Convert 25 Hectares to Acres:
25 × 2.471054 = 61.77635 ac. - Example 4: Convert 100 Hectares (1 Square Kilometer) to Acres:
100 × 2.471054 = 247.10538 ac.

Hectares versus square metres
One hectare is exactly 10,000 square metres. That makes it a convenient metric unit for larger parcels. If you have a plot measurement in square metres, first divide by 10,000 to obtain hectares, or use the AreaConverter calculator directly.
Property and agricultural use
Large farms, rural parcels, forestry areas and official land documents may use hectares even where property listings also display acres. When comparing two documents, make sure you are comparing the same physical parcel and that rounding has not introduced a noticeable difference.
