Formula

mcg = mg × 1000, because 1 mg = 1000 mcg.

Worked example (mathematical example only): 2.5 mg × 1000 = 2500 mcg. And 0.25 mg × 1000 = 250 mcg.

Common slip: mixing up mg and mcg changes a value by a factor of 1000, so always check the unit label. For the reverse direction use the mcg to mg converter.
