- 1000 Micrograms (mcg) = 1 Milligrams (mg)
Convert micrograms to milligrams, the conversion that comes up when a supplement or medication label lists a dose in mcg but you are comparing it to a milligram amount. Enter the micrograms and read the milligrams, and swap for the reverse. This is a unit conversion, not medical advice.
How this is calculated
A milligram is 1000 micrograms, so the tool divides micrograms by 1000 to get milligrams and multiplies by 1000 for the reverse. Micrograms are written mcg on most labels and ug in scientific notation; both mean the same unit.
How to use
- Enter the amount in micrograms.
- Keep mcg to mg, or press Swap for the reverse.
- Read the result in milligrams.
Examples
- A vitamin dose:
1000 mcg = 1 mg - Half that:
500 mcg = 0.5 mg
