Formula

square meters = value x unit factor (1 ft2 = 0.09290304 m2 exactly; 1 acre = 43,560 ft2 = 4,046.8564224 m2)

Understanding Area Conversion

Area units are squares of length units, so their conversion factors are the squares of the length factors: one square foot is 0.3048 squared, or 0.09290304 square meters. Land is usually quoted in acres in the United States and hectares elsewhere. One acre is exactly 43,560 square feet and one hectare is 10,000 square meters.

Tips and Best Practices

  • 1To go from square feet to square meters multiply by 0.0929; the reverse is about 10.764.
  • 2One hectare is about 2.471 acres, and one acre is about 0.4047 hectares.
  • 3Square-unit factors are the length factor squared, so never reuse a length factor directly.

Real-World Example

A 1,200 square foot apartment is 1,200 x 0.09290304 = 111.48 square meters. A 5 acre lot is 2.02 hectares.

Common Mistakes to Avoid

  • Applying a length factor to an area (for example multiplying square feet by 0.3048 instead of 0.0929).
  • Confusing square meters with meters squared in a formula: 2 m squared means 4 m2 when it is a length, but 2 m2 is an area.
  • Using the survey acre for a legal boundary when the international acre is meant; they differ slightly.
