## How to Convert Milligrams to Kilograms

To convert a measurement in milligrams to a measurement in kilograms, divide the weight by the following conversion ratio: 1,000,000 milligrams/kilogram.

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

kilograms = milligrams ÷ 1,000,000

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

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

## What Is a Milligram?

The milligram is a unit of 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 thousandths, or 10-3. Milligrams can be abbreviated as mg; for example, 1 milligram can be written as 1 mg.

## What Is a Kilogram?

One kilogram is equal to 1,000 grams, 2.204623 pounds, or 1/1,000 of a metric ton.

The formal 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 equal to the mass of 1,000 cubic centimeters, or milliliters, 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 thousands, or 103. Kilograms can be abbreviated as kg; for example, 1 kilogram can be written as 1 kg.
