Convert Milligrams (mg) to another unit of weight

The milligram is a unit of mass (acceptable for use as weight on Earth) and is a submultiple of an SI base unit with the symbol mg.

1 milligram is equal to 0.001 g or 1/1000 g (one thousandth of a gram).

There exists 2 submultiples between mg and g - namely the decigram and the centigram but these are not commonly used in everyday life. The milligram is commonly used when expressing parts of a gram; especially in medicine applications.

A mosquito weighs about 2.5 mg, as does a grain of sand.
