About Milligrams and Micrograms
A milligram is one-thousandth of a gram, and a microgram is one-thousandth of a milligram (one-millionth of a gram). Because the "micro" prefix divides by 1000 again, milligram-to-microgram conversion is a clean ×1000 step — no rounding required.
Quick Conversion Tips
Just multiply milligrams by 1000. 1 mg → 1000 mcg; 0.5 mg → 500 mcg; 0.025 mg → 25 mcg. To go the other way, divide the micrograms by 1000. Remember mcg and µg are the same unit.
