square centimetre

Unit: cm²

This is a metric unit used to measure area.

It is possible to draw a shape with an area of 1 cm² by drawing a square measuring 1 centimetre by 1 centimetre.

1 square centimetre is equal to 100 square millimetres (1 cm² = 100 mm²).

We use cm² to measure a small area, for example a photograph.
