How to convert Acres to Square Feet

Area measurements describe surfaces — from apartment floor plans in square meters or square feet to farmland in acres and hectares, and entire countries in square kilometers or square miles.

Every area unit is a length unit squared, which is why conversion factors are large: one acre equals exactly 4,046.8564224 square meters and one hectare is exactly 10,000 square meters.

Formula

ac × 43,560 = ft²

Multiply your acres value by 43,560 to get square feet. For the reverse, divide by the same factor.
