To convert cm² to m², divide by 10,000. 50000 ÷ 10,000 = 5 m². Area units are squared, so convert both length directions; that is why 1 m² equals 10,000 cm². Since area has two dimensions, both length directions are converted, so 100 × 100 = 10,000 cm² make 1 m². Dividing by 10,000 changes square centimetres into square metres; do not divide by only 100 because that would be for length, not area.
