Printable worksheet for practicing metric unit conversions, including meters to kilometers, milliliters to liters, and grams to kilograms.

Let’s solve each conversion step by step. We’ll use the basic metric system rules:

- 1 kilometer (km) = 1,000 meters (m)
- 1 meter (m) = 100 centimeters (cm)
- 1 centimeter (cm) = 10 millimeters (mm)
- 1 liter (L) = 1,000 milliliters (ml)
- 1 kilogram (kg) = 1,000 grams (g)

To convert from a smaller unit to a larger unit → divide by the conversion factor.
To convert from a larger unit to a smaller unit → multiply by the conversion factor.

1a. 2,000 m = ___ km
→ Divide by 1,000: 2,000 ÷ 1,000 = 2

1b. 9 km = ___ m
→ Multiply by 1,000: 9 × 1,000 = 9,000

2a. 9,000 ml = ___ L
→ Divide by 1,000: 9,000 ÷ 1,000 = 9

2b. 3 kg = ___ g
→ Multiply by 1,000: 3 × 1,000 = 3,000

3a. 6 L = ___ ml
→ Multiply by 1,000: 6 × 1,000 = 6,000

3b. 90 mm = ___ cm
→ Divide by 10: 90 ÷ 10 = 9

4a. 6 cm = ___ mm
→ Multiply by 10: 6 × 10 = 60

4b. 4 km = ___ m
→ Multiply by 1,000: 4 × 1,000 = 4,000

5a. 1,000 m = ___ km
→ Divide by 1,000: 1,000 ÷ 1,000 = 1

5b. 2,000 g = ___ kg
→ Divide by 1,000: 2,000 ÷ 1,000 = 2

6a. 50 mm = ___ cm
→ Divide by 10: 50 ÷ 10 = 5

6b. 400 cm = ___ m
→ Divide by 100: 400 ÷ 100 = 4

7a. 4 L = ___ ml
→ Multiply by 1,000: 4 × 1,000 = 4,000

7b. 3 km = ___ m
→ Multiply by 1,000: 3 × 1,000 = 3,000

8a. 10,000 g = ___ kg
→ Divide by 1,000: 10,000 ÷ 1,000 = 10

8b. 2 cm = ___ mm
→ Multiply by 10: 2 × 10 = 20

9a. 10,000 m = ___ km
→ Divide by 1,000: 10,000 ÷ 1,000 = 10

9b. 9,000 g = ___ kg
→ Divide by 1,000: 9,000 ÷ 1,000 = 9

10a. 4,000 g = ___ kg
→ Divide by 1,000: 4,000 ÷ 1,000 = 4

10b. 8,000 ml = ___ L
→ Divide by 1,000: 8,000 ÷ 1,000 = 8
