How to Use the Acreage Calculator

Enter an area, then pick its unit — Sq Ft, Acres, Sq M, or Hectares — from the four buttons above the field. The other three units update immediately.

An acre is an old unit with an oddly specific origin: 43,560 square feet, or one furlong by one chain, roughly the area a team of oxen could plow in a day. Odd as the number looks, it's exact and fixed, not a rounded approximation.

1 acre = 43,560 ft²
1 hectare = 10,000 m²
1 ft² = 0.09290304 m²

Real estate listings, land surveys, and farm plots mix all four units depending on the country, which is the whole reason this calculator exists — a hectare figure from a European listing doesn't mean much until it's converted to acres for a US buyer, or vice versa.
