**Definitions:**

**Gram** (abbreviation: **gm**): is a SI (metric) system unit of mass. Where, at the temperature of melting ice, it is the absolute weight of a volume equal to the hundredth part of a metre cube of pure water.

**Kilogram** (abbreviations: **kg, or kgm**): is a SI (metric) system unit of mass (IPK, also known as "Le Grand K" or "Big K") and equivalent to 1/1000 of one gram. Where, at the temperature of melting ice, one gram is the absolute weight of a volume equal to the hundredth part of a metre cube of pure water.

## How to Convert Grams to Kilograms

*Example: How many kilograms are equivalent to 43.71 grams?*

As;

1 grams = 0.001 kilograms

43.71 grams = Y kilograms

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

Y equals 43.71 times 0.001 over 1

(i.e.) Y = 43.71 * 0.001 / 1 = 0.04371 kilograms

Answer is: 0.04371 kilograms are equivalent to 43.71 grams.
