✍️ Practice
1. Length conversions
1 m = __ cm
1 km = __ m
5 m = __ cm
300 cm = __ m
2. Mass conversions
1 kg = __ g
3 kg = __ g
500 g = __ kg
2500 g = __ kg
3. Capacity conversions
1 L = __ mL
4 L = __ mL
750 mL = __ L
2000 mL = __ L
4. Mixed units
1 m 45 cm in cm =
1 kg 250 g in g =
2 L 500 mL in mL =
2 m 30 cm + 1 m 50 cm in cm =
5. Compare measurements
Type the LARGER one (e.g. "1 km" vs "500 m" → "1 km").
1 km vs 500 m →
2 kg vs 1500 g →
1 L vs 750 mL →
1 m vs 90 cm →
6. Word problems
A car covers 4 km in metres =
1 m 75 cm − 50 cm in cm =
6 km = __ m
1 L 500 mL in mL =
