Ahead of discussing how to convert kilograms to grams, lets define a kilogram. Kilogram(kg) is the base unit of mass in the International System of Units (SI) and it was originally defined as the mass of one liter of water.

While a gram(g) is a metric unit of mass and was formally defined as the absolute weight of a volume of pure water equal to the cube of the hundredth part of a meter, and at the temperature of melting ice.

### Formula to Convert Kilograms to Grams.

In order to convert kg to grams you first need to know the relationship between the two.

It state that 1 kilogram is equivalent to 1000 grams.

Therefore, when changing kg to g, we multiply the kg by 1000.

**Example 1:**

Convert 2 kg to grams.

**= 2 x 1000**

**= 2000 grams**

**Example 2:**

Calculate the mass of a body in grams if it weigh 705.6kg.

Since 1kg is equal to 1,000g therefore,

**= 705.6 x 1,000**

**= 705,600** **grams.**

**Example 3:**

Calculate the weight of the biggest plane in the world, the Antonov, in grams if its take off weight in kilograms is 640,000kg.

1kg = 1000g therefore,

**= 640,000 x 1000**

**= 640,000,000 grams.**
