square metre
Unit: m²
This is a metric unit used to measure area.
It is possible to draw a shape with an area of 1 m² by drawing a square measuring 1 metre by 1 metre.
1 square metre is equal to 10 000 square centimetres (1 m² = 10 000 cm²).
We use m² to measure a large area, for example a room, a piece of land and so on.
