Tips & common mistakes

Quick tips

1 cm² = 100 mm² = 10⁻⁴ m² = 0.155 in².
A square 1 cm on each side contains 1 cm².
For large areas switch to m² or km² early.

Avoid these

Reading cm² as cm in specifications — off by factor involving the length.
Confusing with cc (cubic centimetre, a volume unit).
Assuming cm² and m² are comparable by simple 100 factor — it is 10,000.
