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

To solve this worksheet, we need to convert metric units of measurement. The key is knowing the conversion factors between units.

Here are the main rules we’ll use:
- 1 kilogram (kg) = 1000 grams (g)
- 1 gram (g) = 1000 milligrams (mg) — but we don’t have mg here
- 1 kilometer (km) = 1000 meters (m)
- 1 meter (m) = 100 centimeters (cm)
- 1 centimeter (cm) = 10 millimeters (mm)
- 1 liter (L) = 1000 milliliters (mL)

We multiply when going from larger to smaller units.
We divide when going from smaller to larger units.

Let’s go one by one:

---

1. 0.73 kg = ___ g
→ kg to g → multiply by 1000
0.73 × 1000 = 730 g

2. 0.65 km = ___ cm
→ km to m → ×1000 → then m to cm → ×100 → total ×100,000
0.65 × 100,000 = 65,000 cm

3. 5.0 L = ___ mL
→ L to mL → ×1000
5.0 × 1000 = 5000 mL

4. 0.37 kg = ___ g
→ ×1000
0.37 × 1000 = 370 g

5. 5.6 mL = ___ L
→ mL to L → ÷1000
5.6 ÷ 1000 = 0.0056 L

6. 0.81 mL = ___ L
→ ÷1000
0.81 ÷ 1000 = 0.00081 L

7. 4.6 cm = ___ mm
→ cm to mm → ×10
4.6 × 10 = 46 mm

8. 0.12 mL = ___ L
→ ÷1000
0.12 ÷ 1000 = 0.00012 L

9. 0.18 g = ___ kg
→ g to kg → ÷1000
0.18 ÷ 1000 = 0.00018 kg

10. 1.4 mL = ___ L
→ ÷1000
1.4 ÷ 1000 = 0.0014 L

11. 8.3 L = ___ mL
→ ×1000
8.3 × 1000 = 8300 mL

12. 0.62 kg = ___ g
→ ×1000
0.62 × 1000 = 620 g

13. 0.53 L = ___ mL
→ ×1000
0.53 × 1000 = 530 mL

14. 0.12 cm = ___ km
This is tricky! Let’s break it down:
cm → m → km
First, cm to m: ÷100 → 0.12 ÷ 100 = 0.0012 m
Then, m to km: ÷1000 → 0.0012 ÷ 1000 = 0.0000012 km

Alternatively: 1 km = 100,000 cm → so divide by 100,000
0.12 ÷ 100,000 = 0.0000012 km

15. 4.6 L = ___ mL
→ ×1000
4.6 × 1000 = 4600 mL

16. 0.87 km = ___ mm
km → m → cm → mm? Or directly:
1 km = 1,000,000 mm (because 1 km = 1000 m, 1 m = 1000 mm → 1000×1000=1,000,000)
So: 0.87 × 1,000,000 = 870,000 mm

17. 9.3 kg = ___ g
→ ×1000
9.3 × 1000 = 9300 g

18. 0.15 kg = ___ g
→ ×1000
0.15 × 1000 = 150 g
