The conversions are as follows:

- 1 microgram (mcg or µg) = 0.001 milligrams (mg)
- 1 microgram (mcg) = 1000 nanograms (ng)
- 1 milligram (mg) = 1000 micrograms (mcg)
- 1 gram (g) = 1000 milligrams (mg)

**Converting mcg to mg**

To convert mcg to mg you simply divide your value by 1000 (or multiply by 0.001).
