Micrograms to milligrams
1 microgram in milligrams
1 µg = 0.001 mg
mg = µg × 0.001
To convert micrograms to milligrams, multiply by 0.001. The table below gives the values people look up most often, and the converter works for any number.

How the conversion works
The relationship is mg = µg × 0.001. Both units measure mass, so the conversion is a fixed factor that never changes.
Common questions
- How many milligrams are in one microgram?
- One microgram equals 0.001 milligrams. mg = µg × 0.001.
- How do you convert micrograms to milligrams?
- Use mg = µg × 0.001. So 10 µg is 0.01 mg.
- How many micrograms are in one milligram?
- One milligram equals 1,000 micrograms, which is the reverse of the conversion above.
