Square Footage Formula

Area = Length × Width

Conversions

  • 1 sq ft = 0.0929 sq meters
  • 1 acre = 43,560 sq ft
  • 1 sq yard = 9 sq ft

    • Square footage is the standard unit for measuring floor area in the United States and is essential for estimating flooring, paint, and material costs. For irregularly shaped rooms, divide the space into rectangles, calculate each one separately, and add the results together.
