Area Converter

About this calculator

This tool converts a measurement of area between metric units (square meters, square kilometers, hectares) and imperial/US units (acres, square feet, square yards), applying the fixed conversion factors between each unit pair — for example, one hectare equals exactly 10,000 square meters and about 2.47 acres.

Real estate listings, land surveys, farming and construction plans routinely mix these unit systems depending on the country: hectares and dönüm are common in land and farmland listings, acres dominate in the US and UK property market, and square meters or square feet are used for building floor plans. Buyers comparing a plot of land listed in acres against a domestic listing in square meters, or farmers converting hectares to dönüm, use this calculator to put both figures on the same footing.
