Converting Measurements Worksheet - KS2 Maths Resource - Free Printable

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 1,000 or 100 or 10
To convert from a larger unit to a smaller unit → multiply by 1,000 or 100 or 10

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
