CBSE & NCERT Class 3 Maths Weight and Capacity | Practice Worksheets for class 3
Weight or mass is a measure of how heavy is something. The weights of different things can be measured accurately using standard units. The standard units of measuring weight are kilogram (Kg) and gram (g). We use Kilogram to weigh heavy objects and gram to weigh lighter objects. A weighting balances or scales can be of different types – Pan Balance, Kitchen balance, spring balance, etc.
Note: Standard units are usually accepted units that are used to measure length, weight or capacity
Shopkeepers measure the weight of objects using a weighing balance and weights. Weights are made of metal and come in denominations of 50 kg, 20 Kg, 10 kg, 5 kg, 1 kg, 500 g, 200 g, 100 g, 50 g, 20g, 10 g, and 5 g.
Convert Kilograms into Grams
We can convert one unit to another. There are 1000 grams in 1 kilogram vice versa.
1 Kg = 1000 g
Example: Convert 2kg into grams and 7750g into kg.
2 Kg = 2 multiply by 1000 = 2000 g.
7750 g = 1000 g + 1000 g + 1000 g+ 1000 g + 1000 g + 1000 g + 1000 g + 750 g
= 1 kg + 1 kg + 1 kg + 1 kg + 1 kg + 1 kg + 1 kg + 750 g = 7 kg 750 g
Addition how to add if weight is given in kg and g
Add 60kg 432g and 25kg 530g
Add 86kg 45g and 27kg 757g
Subtract 15kg 430g from 70kg 500g
Sohan weighs 40kg 700g. Riya weighs 35kg 600g. Who weighs more and by how much?
Sohan’s weight = 40kg 700g
Riya’s weight = 35kg 600g
Sohan weighs more by = 40kg 700g – 35kg 600g = 15kg 100g

Capacity is the measure of how much (amount) a container can hold. The capacity of the water bottle is the amount of water that can be filled in the bottle. We use measuring spoons or measuring jugs to measure capacity. The standard units to measure capacity are litre (L) and millilitre (ml). We use millitres to measure a small quantity of liquid like medicine and litres to measure large quantity of liquid.
Convert Litres (L) into milliletres (ml) and vice versa.
1 litre = 1000 milliliters
1l = 1000ml
1000ml = 1l
Example: Convert 7l into ml
7l = 7x 1000ml
Example: Convert 5l 45ml into ml
5l 45ml = 5 x 1000ml + 45ml
= 5000ml + 45ml = 5045ml

Example: Add 24l 250 ml and 12l 400ml
Example: Subtract 5l 350ml from 43l 600ml
