How to Convert Kilograms to Grams

conversion scale showing kilograms and equivalent grams weight values

To convert a kilogram measurement to a gram measurement, multiply the weight by the conversion ratio. One kilogram is equal to 1,000 grams, so use this simple formula to convert:

grams = kilograms × 1,000

The weight in grams is equal to the kilograms multiplied by 1,000.

For example, here's how to convert 5 kilograms to grams using the formula above.
5 kg = (5 × 1,000) = 5,000 g

Kilograms and grams are both units used to measure weight. Keep reading to learn more about each unit of measure.

Kilograms

The definition of the kilogram changed in 2019. Previously, one kilogram was equal to the mass of the platinum-iridium bar, known as the International Prototype of the Kilogram, which was stored in Sèvres, France.

The 2019 SI brochure now defines the kilogram using the Planck constant, and it is defined using the meter and second.[1] It is roughly equal to the mass of 1,000 cubic centimeters of water.

The kilogram, or kilogramme, is the SI base unit for weight, and is also a multiple of the gram. In the metric system, "kilo" is the prefix for 103. Kilograms can be abbreviated as kg, for example 1 kilogram can be written as 1 kg.

Grams

A gram is the mass/weight equal to 1/1,000 of a kilogram, and is roughly equal to the mass of one cubic centimeter of water.

The gram, or gramme, is an SI unit of weight in the metric system. Grams can be abbreviated as g, for example 1 gram can be written as 1 g.
