The formula
ft² = m² × 10.76391042
Where the factor comes from — each unit by its definition, then its size in SI:
1 m² is the SI unit of area.1 ft² = ft² = 0.09290304 m²
Dividing the two SI sizes gives the factor: 10.7639104167 (rounded for display; the underlying ratio is fixed by the definitions). The reverse factor is 0.09290304.
Area in SI is the square metre. Squaring a length conversion squares its factor: 1 ft = 0.3048 m, so 1 ft² is 0.3048² m².
Worked examples
- A shoe sole: 0.02 m² = 0.215278 ft² — 0.02 × 10.76391042 = 0.215278
- A gauge face (1 in²): 0.00064516 m² = 0.00694444 ft² — 0.00064516 × 10.76391042 = 0.00694444
- A small room: 10 m² = 107.639 ft² — 10 × 10.76391042 = 107.639
