About Micrograms and Milligrams

A microgram is one-thousandth of a milligram, and a milligram is one-thousandth of a gram. Since the step between them is exactly ×1,000, micrograms convert to milligrams by simply dividing by 1,000 — a clean decimal shift.

Quick Conversion Tips

Just divide the micrograms by 1,000. 1,000 mcg → 1 mg; 500 mcg → 0.5 mg; 25 mcg → 0.025 mg. To reverse it, multiply the milligrams by 1,000. Remember mcg and µg are the same unit.
