Chapter Overview
1000 millilitres = 1 litre; use millilitres for small amounts and litres for larger amounts.
Jugs and Mugs introduces capacity in millilitres and litres. Learners estimate, measure, compare, and combine liquid quantities while selecting suitable containers and units.
Measuring Capacity
- Capacity is the greatest amount a container can hold.
- A measuring jug has marked intervals for reading volume.
- Read the liquid level at eye level on a flat surface.
- Container height alone does not determine capacity.
Working with Litres
- Convert litres to millilitres by multiplying by 1000.
- Add capacities after expressing them in the same unit.
- Repeated cupfuls can measure a larger container.
- Estimate first, then measure to test the estimate.

Combine Drinks
A jug contains 1 L 250 mL of juice. Another 600 mL is added. How much juice is there?
- 1Write 1 L 250 mL as 1250 mL.
- 2Add 1250 + 600 = 1850 mL.
- 3Convert to litres and millilitres.
Answer
1 L 850 mL
Key Points to Remember
- ✓ Capacity tells how much a container holds
- ✓ 1000 mL equals 1 L
- ✓ Use the same unit before calculating
- ✓ Measure liquid at eye level
Exam Tips
- • Do not confuse capacity with container height
- • Regroup every 1000 mL as 1 L
- • State L or mL in the answer
