Metric Conversion Practice Worksheets - Free Printable

Let's solve each problem on the Metric Conversion Worksheet step by step. The goal is to convert between millimeters (mm), centimeters (cm), meters (m), and kilometers (km). We'll use the following conversion factors:

- 10 mm = 1 cm
- 100 cm = 1 m
- 1000 m = 1 km

We will apply these conversions carefully, keeping track of decimal places as needed.

Solutions:

1) ____ m = 10.16 km
→ 10.16 km × 1000 = 10,160 m

2) ____ cm = 21 mm
→ 21 mm ÷ 10 = 2.1 cm

3) ____ m = 4.9 km
→ 4.9 km × 1000 = 4900 m

4) ____ mm = 9.5 cm
→ 9.5 cm × 10 = 95 mm

5) ____ m = 667 cm
→ 667 cm ÷ 100 = 6.67 m

6) ____ m = 8 km
→ 8 km × 1000 = 8000 m

7) 867 cm = ____ m
→ 867 ÷ 100 = 8.67 m

8) 969 cm = ____ m
→ 969 ÷ 100 = 9.69 m

9) ____ cm = 6.05 m
→ 6.05 m × 100 = 605 cm

10) 6.86 m = ____ cm
→ 6.86 × 100 = 686 cm

11) 300 cm = ____ m
→ 300 ÷ 100 = 3 m

12) ____ cm = 2.89 m
→ 2.89 × 100 = 289 cm

13) 8.37 km = ____ m
→ 8.37 × 1000 = 8370 m

14) 6 km = ____ m
→ 6 × 1000 = 6000 m

15) ____ m = 4.45 km
→ 4.45 × 1000 = 4450 m

16) ____ km = 9280 m
→ 9280 ÷ 1000 = 9.28 km

17) ____ cm = 41.1 mm
→ 41.1 ÷ 10 = 4.11 cm

18) 7.1 m = ____ cm
→ 7.1 × 100 = 710 cm

19) 8.04 cm = ____ mm
→ 8.04 × 10 = 80.4 mm

20) 6.1 m = ____ cm
→ 6.1 × 100 = 610 cm

21) 1017 cm = ____ m
→ 1017 ÷ 100 = 10.17 m

22) ____ mm = 9 cm
→ 9 × 10 = 90 mm

23) 450 cm = ____ m
→ 450 ÷ 100 = 4.5 m

24) 5000 m = ____ km
→ 5000 ÷ 1000 = 5 km

25) ____ mm = 3 cm
→ 3 × 10 = 30 mm

26) 9.8 km = ____ m
→ 9.8 × 1000 = 9800 m

27) 3 km = ____ m
→ 3 × 1000 = 3000 m

28) 637 cm = ____ m
→ 637 ÷ 100 = 6.37 m

29) ____ cm = 52 mm
→ 52 ÷ 10 = 5.2 cm

30) ____ km = 3000 m
→ 3000 ÷ 1000 = 3 km

🔍 Explanation Summary:

- When converting larger units → smaller units (e.g., km → m), multiply.
- When converting smaller units → larger units (e.g., cm → m), divide.
- Use the appropriate factor:
- mm ↔ cm: divide or multiply by 10
- cm ↔ m: divide or multiply by 100
- m ↔ km: divide or multiply by 1000
