Grade 6 Measurement Worksheets: Convert metric units - mixed ... - Free Printable

Let’s go through each problem one by one. We’ll convert metric units using the standard conversion factors:

- 1 kg = 1000 g
- 1 km = 100,000 cm (because 1 km = 1000 m and 1 m = 100 cm → 1000 × 100 = 100,000)
- 1 L = 1000 mL
- 1 mL = 0.001 L
- 1 cm = 10 mm
- 1 km = 1,000,000 mm (because 1 km = 1000 m and 1 m = 1000 mm → 1000 × 1000 = 1,000,000)

Now let’s solve each:

1. 0.73 kg = ? g
→ Multiply by 1000: 0.73 × 1000 = 730 g

2. 0.65 km = ? cm
→ Multiply by 100,000: 0.65 × 100,000 = 65,000 cm

3. 5.0 L = ? mL
→ Multiply by 1000: 5.0 × 1000 = 5000 mL

4. 0.37 kg = ? g
→ Multiply by 1000: 0.37 × 1000 = 370 g

5. 5.6 mL = ? L
→ Divide by 1000: 5.6 ÷ 1000 = 0.0056 L

6. 0.81 mL = ? L
→ Divide by 1000: 0.81 ÷ 1000 = 0.00081 L

7. 4.6 cm = ? mm
→ Multiply by 10: 4.6 × 10 = 46 mm

8. 0.12 mL = ? L
→ Divide by 1000: 0.12 ÷ 1000 = 0.00012 L

9. 0.18 g = ? kg
→ Divide by 1000: 0.18 ÷ 1000 = 0.00018 kg

10. 1.4 mL = ? L
→ Divide by 1000: 1.4 ÷ 1000 = 0.0014 L

11. 8.3 L = ? mL
→ Multiply by 1000: 8.3 × 1000 = 8300 mL

12. 0.62 kg = ? g
→ Multiply by 1000: 0.62 × 1000 = 620 g

13. 0.53 L = ? mL
→ Multiply by 1000: 0.53 × 1000 = 530 mL

14. 0.12 cm = ? km
→ First, convert cm to meters: 0.12 cm = 0.0012 m
Then, convert meters to km: 0.0012 ÷ 1000 = 0.0000012 km
*(Or directly: 0.12 cm ÷ 100,000 = 0.0000012 km)*

15. 4.6 L = ? mL
→ Multiply by 1000: 4.6 × 1000 = 4600 mL

16. 0.87 km = ? mm
→ Multiply by 1,000,000: 0.87 × 1,000,000 = 870,000 mm

17. 9.3 kg = ? g
→ Multiply by 1000: 9.3 × 1000 = 9300 g

18. 0.15 kg = ? g
→ Multiply by 1000: 0.15 × 1000 = 150 g

1. 730 g
