Convert metric units of measurement worksheet for Grade 6 students.

Let's solve each problem step by step in the "Convert metric units of measurement" worksheet. We'll use standard metric conversions:

Metric Conversions:

- Mass:
- 1 kg = 1000 g
- 1 g = 1000 mg
- Volume:
- 1 L = 1000 mL
- Length:
- 1 m = 100 cm
- 1 cm = 10 mm
- 1 km = 1000 m

Now, let’s solve each question:

---

1. 0.73 kg = ________ g
→ Multiply by 1000:
$ 0.73 \times 1000 = 730 $
✔ 730 g

2. 0.65 kg = ________ cm
✘ This is incorrect. kg (kilograms) is a unit of mass, and cm (centimeters) is a unit of length. You cannot convert kilograms to centimeters.
→ Invalid conversion.
✘ Not possible

3. 5.0 L = ________ mL
→ Multiply by 1000:
$ 5.0 \times 1000 = 5000 $
✔ 5000 mL

4. 0.37 kg = ________ g
→ Multiply by 1000:
$ 0.37 \times 1000 = 370 $
✔ 370 g

5. 5.6 mL = ________ L
→ Divide by 1000:
$ 5.6 \div 1000 = 0.0056 $
✔ 0.0056 L

6. 0.81 mL = ________ L
→ Divide by 1000:
$ 0.81 \div 1000 = 0.00081 $
✔ 0.00081 L

7. 4.6 cm = ________ mm
→ Multiply by 10:
$ 4.6 \times 10 = 46 $
✔ 46 mm

8. 0.12 L = ________ mL
→ Multiply by 1000:
$ 0.12 \times 1000 = 120 $
✔ 120 mL

9. 0.18 g = ________ kg
→ Divide by 1000:
$ 0.18 \div 1000 = 0.00018 $
✔ 0.00018 kg

10. 1.4 mL = ________ L
→ Divide by 1000:
$ 1.4 \div 1000 = 0.0014 $
✔ 0.0014 L

11. 8.3 L = ________ mL
→ Multiply by 1000:
$ 8.3 \times 1000 = 8300 $
✔ 8300 mL

12. 0.62 kg = ________ g
→ Multiply by 1000:
$ 0.62 \times 1000 = 620 $
✔ 620 g

13. 0.53 L = ________ mL
→ Multiply by 1000:
$ 0.53 \times 1000 = 530 $
✔ 530 mL

14. 0.12 cm = ________ km
✘ This is not a valid direct conversion.
First, convert cm to m:
$ 0.12 \text{ cm} = 0.0012 \text{ m} $
Then to km:
$ 0.0012 \div 1000 = 0.0000012 \text{ km} $
But this is extremely small.
✔ 0.0000012 km (or $ 1.2 \times 10^{-6} $ km)
→ However, such a conversion is not practical — likely a typo or error.

15. 4.6 L = ________ mL
→ Multiply by 1000:
$ 4.6 \times 1000 = 4600 $
✔ 4600 mL

16. 0.87 m = ________ mm
→ Multiply by 1000:
$ 0.87 \times 1000 = 870 $
✔ 870 mm

17. 9.3 kg = ________ g
→ Multiply by 1000:
$ 9.3 \times 1000 = 9300 $
✔ 9300 g

18. 0.15 kg = ________ g
→ Multiply by 1000:
$ 0.15 \times 1000 = 150 $
✔ 150 g

Notes:

- Question #2 and #14 are problematic due to mismatched units.
- #2: kg → cm → Not possible
- #14: cm → km → Technically possible but impractical; probably meant to be m → km or cm → m
- Always ensure you're converting within the same type of measurement (mass, volume, length).
