Metric Conversion Worksheets - Math Monks - Free Printable

Let’s solve each problem step by step. We’re converting between metric units, so we’ll use the standard conversion factors:

- 1 kg = 1000 g → to go from g to kg, divide by 1000; from kg to g, multiply by 1000
- 1 m = 100 cm → to go from cm to m, divide by 100; from m to cm, multiply by 100
- 1 L = 1000 mL → to go from mL to L, divide by 1000; from L to mL, multiply by 1000
- 1 km = 1000 m → to go from m to km, divide by 1000; from km to m, multiply by 1000
- 1 cm = 10 mm → to go from mm to cm, divide by 10; from cm to mm, multiply by 10

Now let’s do each one:

1. 3680 g = ? kg → 3680 ÷ 1000 = 3.68
2. 0.67 kg = ? g → 0.67 × 1000 = 670
3. 101 cm = ? m → 101 ÷ 100 = 1.01
4. 8.08 L = ? mL → 8.08 × 1000 = 8080
5. 158 mm = ? cm → 158 ÷ 10 = 15.8
6. 7.85 km = ? m → 7.85 × 1000 = 7850
7. 13570 mL = ? L → 13570 ÷ 1000 = 13.57
8. 14.9 cm = ? mm → 14.9 × 10 = 149
9. 608 m = ? km → 608 ÷ 1000 = 0.608
10. 30.5 m = ? cm → 30.5 × 100 = 3050
11. 2750 cm = ? m → 2750 ÷ 100 = 27.5
12. 5.68 km = ? m → 5.68 × 1000 = 5680
13. 800 g = ? kg → 800 ÷ 1000 = 0.8
14. 4.82 L = ? mL → 4.82 × 1000 = 4820
15. 8700 mL = ? L → 8700 ÷ 1000 = 8.7
16. 0.09 kg = ? g → 0.09 × 1000 = 90
17. 1520 mm = ? cm → 1520 ÷ 10 = 152
18. 12 cm = ? mm → 12 × 10 = 120
19. 2080 m = ? km → 2080 ÷ 1000 = 2.08
20. 20.8 m = ? cm → 20.8 × 100 = 2080

All calculations checked and verified.
