Measuring Capacity

Capacity is a measure of how much space something takes up. We use measuring spoons or measuring jugs to measure capacity. We often measure capacity in liter or milliliter. We measure small quantity of liquid in milliliters and large quantity of liquid in liters.

The standard unit of length is ‘Liter’.

1 liter = 1000 milliliters

We use ‘ml’ for milliliter, ‘l’ for liter in short form.

1l = 1000ml

Or

1000ml = 1l

Addition and Subtraction of units of capacity

Arrange the number in column according to the units. First add smaller unit then add larger unit.

Example 1:

Add 24l 140ml and 35l 130ml

Example 2:

Subtract 14l 130ml from 35l 130ml

Example 3:

A shopkeeper brought 77l 550ml of milk in the month of January and 23l 350ml in the month of February. How much milk did he bring in 2 months?

Solution:

Milk bought in the month of January = 77l 550ml

Milk bought in the month of February =23l 350ml

Milk bought in 2 months = 77l 550ml + 23l 350ml

Conversions:

To convert liters into milliliters, we multiply the given number of liters by 1000.

Example1: Convert 5l into ml

5l = 5 x 1000ml

    = 5000ml

Example 2: Convert 4l 85ml into ml

4l 85ml = 4 x 1000ml + 85ml

            = 4000ml + 85ml 

            = 4085ml
