How these units are defined
Area factors are the square of the length factor: 1 ft = 0.3048 m, so 1 ft² = 0.3048² = 0.09290304 m². The acre is 43,560 ft² (4,046.8564224 m²) and the hectare 10,000 m².

Worked examples
- 1 Square Meter = 10.76391 Square Foot
- 10 Square Meter = 107.6391 Square Foot
- 50 Square Meter = 538.19552 Square Foot
- 100 Square Meter = 1,076.391 Square Foot
Common mistakes
- Do not apply a length factor to an area: 100 m² is 1,076.39 ft², not 328 ft² (100 × 3.28).
- A plot described as "20 × 30 ft" is 600 ft²; convert each side to metres first or convert the area afterwards — never just one side.
