## How to Convert Kilograms to Grams

*Example: How many grams are equivalent to 87.21 kilograms?*

As;

1 kilograms = 1000 grams

87.21 kilograms = Y grams

Assuming Y is the answer, and by criss-cross principle;

Y equals 87.21 times 1000 over 1

(i.e.) Y = 87.21 * 1000 / 1 = 87210 grams

Answer is: 87210 grams are equivalent to 87.21 kilograms.
