## How to Convert Milligrams to Kilograms

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

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

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

**For example,**here's how to convert 5,000,000 milligrams to kilograms using the formula above.

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

## Milligrams

The milligram is the mass equal to 1/1,000 of a gram, or 0.0154 grains.

The milligram, or milligramme, is an SI unit of weight in the metric system. In the metric system, "milli" is the prefix for 10^{-3}. Milligrams can be abbreviated as *mg*; for example, 1 milligram can be written as 1 mg.

## Kilograms

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 SÃ¨vres, 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 10^{3}. Kilograms can be abbreviated as *kg*; for example, 1 kilogram can be written as 1 kg.
