Length units
Practise mm, cm, dm, m, and km with conversions, comparisons, and short calculations.
How to solve this
- Use the metric ladder: 1 cm = 10 mm, 1 dm = 10 cm, 1 m = 100 cm, and 1 km = 1000 m.
- For comparisons, convert both lengths to the same unit before choosing <, >, or =.
- Mixed answers show the same amount in two units: 350 cm is 3 m 50 cm.
Examples
1 m = __ cm
100
4 km = __ m
4000
350 cm
3 m 50 cm
