How the conversion works

Every unit is converted through square meters using exact definitions, then shown rounded to a sensible number of decimals.

  • 1 sq ft = 144 sq in = 0.111111 sq yd
  • 1 acre = 43,560 sq ft = 4,046.8564224 m²
  • 1 hectare = 10,000 m²; 1 sq km = 100 ha; 1 sq mi = 640 acres

US and UK listings quote floor area in square feet, while most of the world uses square meters, so buyers comparing listings need both.

Tips

  • Check whether a listing means usable floor area or the whole plot: land is often quoted in acres or hectares.
  • Round numbers can hide a lot: 1,000 sq ft is 92.9 m², but 92.9 m² is not a standard apartment size label.
  • For rooms, measure length × width in the same unit before converting.
