Compare land areas across unit systems

Acres are widely used for land in the United States and United Kingdom, while hectares are the metric standard for farms, forests, and large parcels. This converter applies the international acre relationship in both directions and gives a reference table for common whole-acre amounts.

With the default value, 5 acres converts to 2.02343 hectares. Reversing the direction shows that 1 hectare converts to 2.47105 acres. The calculation changes only the area unit, so a surveyed parcel keeps the same physical extent after conversion.

Private planning, separate from surveying

Entered acreage stays on your device and is not associated with an address or account. The result is appropriate for comparisons and preliminary planning, but it does not establish a legal boundary. Deeds, cadastral records, and professional surveys remain the authority for parcel area.
