How to convert micrograms to milligrams
mg = µg ÷ 1,000
To convert micrograms to milligrams, divide the number of micrograms by 1,000.
Example: 42 µg to mg
- Start with the value in micrograms: 42 µg.
- Divide by 1,000: 42 ÷ 1,000 = 0.042.
- Result: 42 micrograms = 0.042 milligrams.
Going the other way, 1 milligram = 1,000 micrograms, so to convert milligrams back to micrograms you multiply by the same number. See milligrams to micrograms.
