Convert Milligrams To Grams
|
This measurement conversion is based on a simple rule: 1 mg = 0.001 g One-millionth of a kilogram is 1 mg (one milligram)
The gram, symbol g, is a unit of mass. Originally defined as "the absolute weight of a volume of pure water equal to the cube of the hundredth part of a metre, and at the temperature of melting ice" (later 4 ℃), a gram is now defined as one one-thousandths of the SI base unit, the kilogram, or 1x10-3 kg, which itself is defined as being equal to the mass of a physical prototype preserved by the International Bureau of Weights and Measures.
