How to convert micrograms to milligrams

1 μg = (1/1000) mg = 0.001 mg

This implies that one microgram is equivalent to 1000 milligrams (mg).

The mass in milligrams is calculated by dividing the mass in micrograms by 1000. It is expressed as;

M (mg) = M (μg) / 1000

Using the example above;

Convert 200 micrograms to milligrams,

The calculation will be;

M (mg) = 200 μg / 1000

= 0.2 milligrams (mg)

The Micrograms to Milligrams conversion table can be used to determine common conversions from micrograms to milligrams on a scale of 0 μg to 1000 μg.

How many milligrams in a microgram?

The mass units' conversion factor of micrograms to milligrams is 0.001. If you want to find out the number of milligrams in one microgram, you multiply the value in micrograms by the conversion factor.

1 μg = 0.001 mg

This means that there are 0.001 milligrams in one microgram. For example, how many milligrams are in 3000 micrograms?

= 3000 x 0.001

= 3 mg

Therefore, there are 3 milligrams in 3000 micrograms.

A milligram is abbreviated as "mg" and it is equivalent to a millionth of a kilogram. A microgram is used in nutritional supplement and pharmaceutical labeling, typically abbreviated as "mcg" to avoid confusion. This is because the technical disciplines do not recognize the "µ" prefix.
