How to convert grams to milligrams

This calculator uses a simple formula when performing the conversions from grams to milligrams.

1 g = 1000 mg

It means that one gram is made up of one thousand milligrams.

The mass in milligrams is calculated by multiplying the mass in grams by 1000. It can be expressed as;

M (mg) = M (g) x 1000

Using the example above;

Convert 5 grams to milligrams

The calculation will be;

M (mg) = 5g x 1000

= 5000 milligrams (mg)

How many milligrams are in a gram?

The mass unit conversion factor of grams to milligrams is 1000. To determine the number of milligrams that are in grams, we multiply the value in grams by 1000.

1 gram = 1000 milligrams

This implies that there are one thousand milligrams in one gram.

Both gram and milligram are mass units in the metric system. The prefix "Milli" in the metric system means "one-thousandth of". When the prefix "Milli" is replaced with 1000, it makes one milligram to be "1000th" of a gram i.e. 1000 milligrams in one gram.

A gram is a unit mass in the metric system that is one-thousandth of a kilogram. One gram is equivalent to the mass one cubic centimeter of one milliliter of water. A milligram is mostly used in the field of pharmacy and medicine.  It is abbreviated as "mg" and there are one million milligrams in one kilogram.
