Practice Questions
Q1. Convert 350 cm to metres.
3.5 m (divide by 100).
Q2. Convert 2 km to metres.
2,000 m (multiply by 1000).
Q3. Which is longer: 45 mm or 4 cm?
45 mm (4 cm = 40 mm, so 45 mm is longer).
Q4. A pencil is 15 cm long. How many mm is that?
150 mm.
Q5. Which unit would you use to measure the distance between two cities?
Kilometres (km).
Why These Help
Converting in both directions (small to big units and big to small) is exactly what trips students up if only practised one way — these questions cover both.
Frequently Asked Questions
Are these questions from the official textbook?
No — original practice questions on the same length-conversion ideas from the chapter.
What’s a simple trick to remember mm, cm, m, km in order?
Each unit is 10, 100, or 1000 times the smaller one — mm to cm is ×10, cm to m is ×100, m to km is ×1000.
