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.

| 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.
