How it's calculated

How to calculate square meters

A square meter is the area of a square with 1 m sides.

  1. 1

    Measure length and width

    Use the same unit for both. The calculator turns centimeters, feet and inches into meters before multiplying.

  2. 2

    Multiply

    Square meters = length × width. A 12 × 10 ft room is 3.6576 × 3.048 m, or 11.15 m².

  3. 3

    Convert from square feet

    Multiply square feet by 0.0929: 1,000 sq ft is 92.9 m². The other way, multiply m² by 10.764.

  4. 4

    Hectares and acres

    A hectare is 10,000 m² and an acre is 4,046.86 m², or 43,560 sq ft.
