📏 Part 1: Basic Unit Conversions

1. Convert these measurements to metres:

a) 5000 mm = _______ m

b) 350 cm = _______ m

c) 2.5 km = _______ m

2. Convert these measurements to centimetres:

a) 40 mm = _______ cm

b) 3.2 m = _______ cm

c) 0.8 km = _______ cm

3. Which conversion is correct?

7500 mm = 7.5 m

7500 mm = 75 m

7500 mm = 750 m

4. A car travels 12.5 km. How many metres did it travel?

🚗 Part 2: Real-World Problems

5. Sarah is building a fence. She needs three pieces of wood: 2.5 m, 180 cm, and 1500 mm. What is the total length in metres?

6. A running track is 400 m long. Jake runs 5 laps. How many kilometres did he run in total?

7. Which measurements are equivalent? (Tick all that apply)

2000 mm and 2 m

1.5 km and 1500 m

250 cm and 2.5 m

3000 mm and 30 cm

8. Extension: A rectangular garden is 15.5 m long and 850 cm wide. What is the perimeter in kilometres?

9. Pattern Investigation: Complete this conversion pattern and explain the rule:

1 km = _______ m = _______ cm = _______ mm

10. Create Your Own: Write a real-world problem that requires converting between at least two different metric length units. Then solve it.
