How to Convert Kilograms to Milligrams

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

milligrams = kilograms × 1,000,000

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

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

5 kg = (5 × 1,000,000) = 5,000,000 mg
