How to Convert Kilograms to Milligrams
To convert a kilogram measurement to a milligram measurement, multiply 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 milligrams is equal to the kilograms multiplied by 1,000,000.
How Many Milligrams Are in a Kilogram?
There are 1,000,000 milligrams in a kilogram, which is why we use this value in the formula above.

Kilograms and milligrams 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. 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.
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.
