Metric length conversion practice worksheet with problems converting between km, m, and cm.

Let's solve each of the metric length conversion problems step by step. We'll use the following key conversions:

- 1 kilometer (km) = 1,000 meters (m)
- 1 meter (m) = 100 centimeters (cm)

---

Part 1: Kilometers to Meters

1. 1 km = ? m
→ $1 \times 1000 = 1000$ m
✔ 1000 m

2. 3 km 312 m = ? m
→ $3 \times 1000 + 312 = 3000 + 312 = 3312$ m
✔ 3312 m

3. 4 km = ? m
→ $4 \times 1000 = 4000$ m
✔ 4000 m

4. 13 km 27 m = ? m
→ $13 \times 1000 + 27 = 13000 + 27 = 13027$ m
✔ 13027 m

5. 7 km = ? m
→ $7 \times 1000 = 7000$ m
✔ 7000 m

6. 7 km 123 m = ? m
→ $7 \times 1000 + 123 = 7000 + 123 = 7123$ m
✔ 7123 m

7. ? km = 18,000 m
→ $18,000 \div 1000 = 18$ km
✔ 18 km

8. 22 km 22 m = ? m
→ $22 \times 1000 + 22 = 22000 + 22 = 22022$ m
✔ 22022 m

9. ? km = 17,000 m
→ $17,000 \div 1000 = 17$ km
✔ 17 km

10. 915 km 8 m = ? m
→ $915 \times 1000 + 8 = 915000 + 8 = 915008$ m
✔ 915008 m

Part 2: Meters and Centimeters

11. 1 m = ? cm
→ $1 \times 100 = 100$ cm
✔ 100 cm

12. 3 m 56 cm = ? cm
→ $3 \times 100 + 56 = 300 + 56 = 356$ cm
✔ 356 cm

13. 3 m = ? cm
→ $3 \times 100 = 300$ cm
✔ 300 cm

14. 7 m 45 cm = ? cm
→ $7 \times 100 + 45 = 700 + 45 = 745$ cm
✔ 745 cm

15. 80 m = ? cm
→ $80 \times 100 = 8000$ cm
✔ 8000 cm

16. 67 m 7 cm = ? cm
→ $67 \times 100 + 7 = 6700 + 7 = 6707$ cm
✔ 6707 cm

17. ? m = 12,000 cm
→ $12,000 \div 100 = 120$ m
✔ 120 m

18. 14 m 8 cm = ? cm
→ $14 \times 100 + 8 = 1400 + 8 = 1408$ cm
✔ 1408 cm

19. ? m = 2,400 cm
→ $2,400 \div 100 = 24$ m
✔ 24 m

20. 120 m 46 cm = ? cm
→ $120 \times 100 + 46 = 12000 + 46 = 12046$ cm
✔ 12046 cm
