How to Convert Grams to Kilograms

To convert a gram measurement to a kilogram measurement, divide the weight by the conversion ratio.

Since one kilogram is equal to 1,000 grams, you can use this simple formula to convert:

kilograms = grams ÷ 1,000

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

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

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


A gram is the mass/weight equal to 1/1,000 of a kilogram and is roughly equivalent 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.


The definition of the kilogram changed in 2019. One kilogram was previously 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.
