Kilograms and grams → grams

Method: Simply add three zeroes to the right of the weight in kg, to convert kg into g.

Example 1: Convert 5 kg into grams.

1 kg = 1000 g

5 kg = (5 × 1000) g = 5000 g

Answer: 5000 g

Example 2:Convert 6 kg 470 g into grams.

6 kg = (6 × 1000) g

= 6000 g

6 kg 470 g = 6000 g + 470 g = 6470 g

Answer: 6470 g

Exercise 10.1

1. 10 kg______________
2. 1 kg 321 g______________

4. 3 kg 430 g______________
5. 18 kg 253 g______________
6. 32 kg 560 g______________

Grams to kilograms and grams

Method 1: When the weight is exactly divisible by 1000, simply remove three zeroes from the right of the weight in g, to convert g into kg.

Example 3: Convert 9000 g into kg.

9000 g = 1 kg

9000 g = (9000 ÷ 1000) kg

= 9 kg

Method 2: When the measure in grams is not exactly divisible by 1000, i.e. when there is a remainder, then the quotient is written in kg, and the remainder is written in g. Or simply write last three digits in grams and remaining digits in kilograms.

Example 4: Convert 4640 g into kilograms and grams.

4640 ÷ 1000, Q = 4 and R = 640

Answer: 4640 g = 4 kg 640 g
