12 Capacity

Warm Up

● The quantity of a liquid in a container is the capacity or volume. For example, a juice pack
of 200 mL.
● Capacity of a container tells us how much of a liquid it can hold.

● The units of capacity are litre and millilitre which are denoted as ‘L‘ and 'mL'.

We measure the quantities of various liquids such as petrol, juice, milk, etc. with the help
of containers whose capacity is known.

Units of Capacity

1. The standard unit of capacity is litre which is denoted as ‘L‘.

2. Millilitre is the smallest unit of capacity which is denoted as 'mL'.

Commonly used Containers to Measure Capacity

Liquids like oil, petrol, milk, juice, etc. are measured using standard sized containers as
shown below.

5 L 1 L 500 mL 200 mL 100 mL 50 mL

Conversion of Capacity
1 L = 1000 mL

● To convert litres into millilitres, multiply the given number of litres by 1000. For
example,

5 L = (5 × 1000) mL = 5000 mL
