How to convert square feet to square metres
One square foot equals 0.092903 square metres, so multiply the number of square feet by 0.092903:
m² = ft² × 0.092903
ft² = m² ÷ 0.092903 (1 m² = 10.7639 ft²)
Example: 100 ft² → 100 × 0.092903 = 9.2903 m².
Going the other way, divide by 0.092903, or multiply by 10.7639; the square metres to square feet converter does it for you.
