What does mcg stand for?

• A. milligram
• B. microgram
• C. gram
• D. kilogram

Answer: (B)

Understanding metric prefixes and mass units helps decode units like mcg. mcg stands for microgram, a mass equal to one millionth of a gram. That makes it much smaller than a milligram (1 mg = 1000 mcg), and a gram equals 1,000,000 mcg, while a kilogram equals 1,000,000,000 mcg. In medical and veterinary contexts, tiny doses are often given in micrograms, so mcg is the common abbreviation used to convey those small amounts. So, mcg means microgram.
