72 mm to cm

72 mm = 7.2 cm

Divide by 10, because one centimeter holds exactly 10 millimeters: 72 mm ÷ 10 = 7.2 cm.

Multiply by 10, the inverse operation: 7.2 cm × 10 = 72 mm. Converting both ways is the quickest check that the figure is right.

72 mm = 0.72 dm = 0.072 m = 0.000072 km. Each step up the metric ladder moves the decimal point further left.
