Grams to Milligrams

A gram is the mass/weight equal to 1/1,000 of a kilogram and is roughly equivalent to the mass of one cubic centimeter of water.

The gram, or gramme, is an SI unit of weight in the metric system. Grams can be abbreviated as g; for example, 1 gram can be written as 1 g.

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.

How to convert Grams to Milligrams

1 gram (g) is equal to 1000 milligrams (mg).

1 g = 1000 mg

The mass m in milligrams (mg) is equal to the mass m in grams (g) times 1000:

m_(mg) = m_(g) × 1000

Example

Convert 5 g to milligrams:

m_(mg) = 5 g × 1000 = 5000 mg

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. It is roughly equal to the mass of 1,000 cubic centimeters of water.

The kilogram, or kilogramme, is the SI
