Conversion of Weight
© G. Ram Books (P.) Ltd.©
1 kilogram = 1000 grams

● To convert the given weight in kilogram to gram, multiply the number of kilograms
by 1000.

For example, 8 kg = 8 × 1000 = 8000 g; 15 kg = 15 × 1000 = 15000 g

● To convert kilogram and gram into gram, we multiply the number of kilogram by
1000 and then add it to the number of grams.

For example, 6 kg 70 g = (6 × 1000) g + 70 g = 6000 g + 70 g = 6070 g.

● To convert grams into kilograms and grams, separate the thousands and write them
as kg.

7090 g = (7000 + 90) g = 7 kg + 90 g = 7 kg 90 g

4789 g = 4000 g + 789 g = 4 kg + 789 g = 4 kg 789 g (1000 g = 1 kg)

8079 = 8000 g + 79 g = 8 kg + 79 g = 8 kg 79 g.
