Converter from m to m2 and m2 to m

Calculate area in m² from width × length in metres. A 3×4 m room is 12 m² (≈ 129.2 ft²).

How to convert metres to square metres

m² = width(m) × length(m). Linear metres alone are not an area — you need two perpendicular dimensions.

Common mistake

Treating m and m² as interchangeable. 4 linear metres of 1 m wide material cover 4 m²; the same 4 m at 0.5 m width cover only 2 m².
