Tips & common mistakes

Quick tips

1 m² ≈ 10.76 ft².
Multiply length × width in metres to get m².
For a mental image: a square tile 1 m × 1 m covers 1 m².

Avoid these

Writing m2 or m^2 in formal documents — the correct notation is m².
Confusing m² with m — one is area, the other length.
Treating 2 m² as twice 1 m² in side length — it is actually √2 × 1 m on each side.
