Milligrams to micrograms

1 milligram in micrograms
1 mg = 1,000 µg
µg = mg × 1,000

To convert milligrams to micrograms, multiply by 1,000. The table below gives the values people look up most often, and the converter works for any number.

Milligrams to micrograms table

Common milligram values converted to micrograms.
Milligrams Micrograms
1 mg 1,000
2 mg 2,000
3 mg 3,000
4 mg 4,000
5 mg 5,000
10 mg 10,000
15 mg 15,000
20 mg 20,000
25 mg 25,000
30 mg 30,000
40 mg 40,000
50 mg 50,000
75 mg 75,000
100 mg 100,000
250 mg 250,000
500 mg 500,000
1,000 mg 1,000,000

How the conversion works

The relationship is µg = mg × 1,000. Both units measure mass, so the conversion is a fixed factor that never changes.

Common questions

How many micrograms are in one milligram?
One milligram equals 1,000 micrograms. µg = mg × 1,000.
How do you convert milligrams to micrograms?
Use µg = mg × 1,000. So 10 mg is 10,000 µg.
How many milligrams are in one microgram?
One microgram equals 0.001 milligrams, which is the reverse of the conversion above.
