The microgram (mcg) is an extremely small unit of mass, equal to one-millionth of a gram. It is often used to measure vitamins, minerals, and pharmaceuticals where tiny amounts make a big difference.
The milligram (mg) is larger, equal to one-thousandth of a gram. It is a more commonly used unit for drug dosages, chemical substances, and nutritional values.
To convert micrograms to milligrams, use this simple formula:
Milligrams (mg) = Micrograms (mcg) ÷ 1,000
Example: To convert 5,000 mcg to mg, divide:
5,000 ÷ 1,000 = 5 mg
A single strand of human hair weighs about 500 mcg.
