Grade 5 revision worksheet focusing on converting metric units of measurement.

Let’s solve each problem step by step. We’ll use the basic metric conversion rules:

- 1 kg = 1000 g → to convert g to kg, divide by 1000; to convert kg to g, multiply by 1000
- 1 L = 1000 mL → to convert mL to L, divide by 1000; to convert L to mL, multiply by 1000
- 1 m = 1000 mm → to convert mm to m, divide by 1000
- 1 m = 100 cm → to convert m to cm, multiply by 100

Task 1: Convert the following units

1. 6.3 g = ? kg
Divide by 1000 → 6.3 ÷ 1000 = 0.0063 kg

2. 0.44 L = ? mL
Multiply by 1000 → 0.44 × 1000 = 440 mL

3. 5.6 mL = ? L
Divide by 1000 → 5.6 ÷ 1000 = 0.0056 L

4. 0.39 kg = ? g
Multiply by 1000 → 0.39 × 1000 = 390 g

5. 9.7 mm = ? m
Divide by 1000 → 9.7 ÷ 1000 = 0.0097 m

6. 0.33 mL = ? L
Divide by 1000 → 0.33 ÷ 1000 = 0.00033 L

7. 0.47 g = ? kg
Divide by 1000 → 0.47 ÷ 1000 = 0.00047 kg

8. 5.0 kg = ? g
Multiply by 1000 → 5.0 × 1000 = 5000 g

9. 0.24 kg = ? g
Multiply by 1000 → 0.24 × 1000 = 240 g

10. 0.11 m = ? cm
Multiply by 100 → 0.11 × 100 = 11 cm

11. 0.17 kg = ? g
Multiply by 1000 → 0.17 × 1000 = 170 g

12. 0.22 kg = ? g
Multiply by 1000 → 0.22 × 1000 = 220 g

13. 7.4 mL = ? L
Divide by 1000 → 7.4 ÷ 1000 = 0.0074 L

14. 3.7 mL = ? L
Divide by 1000 → 3.7 ÷ 1000 = 0.0037 L

Task 2: Convert the following units

These ask for mixed units (like liters and milliliters together).

Remember:
- The whole number part stays as liters.
- The decimal part × 1000 gives milliliters.

1. 1.6 L = ___ L ___ mL
Whole number: 1 L
Decimal: 0.6 × 1000 = 600 mL
→ 1 L 600 mL

2. 6 L 55 mL = ___ L
55 mL = 55 ÷ 1000 = 0.055 L
Add to 6 L → 6 + 0.055 = 6.055 L

3. 3.033 L = ___ L ___ mL
Whole number: 3 L
Decimal: 0.033 × 1000 = 33 mL
→ 3 L 33 mL

4. 7.5 L = ___ L ___ mL
Whole number: 7 L
Decimal: 0.5 × 1000 = 500 mL
→ 7 L 500 mL

5. 235.50 L = ___ mL
Multiply by 1000 → 235.50 × 1000 = 235500 mL
