How many micrograms are in 2.5 mg?

• A. 250 mcg
• B. 25 mcg
• C. 25000 mcg
• D. 2500 mcg

Answer: (D)

Converting between milligrams and micrograms is a straightforward scale conversion: 1 mg equals 1000 mcg. So to turn milligrams into micrograms, you multiply by 1000. For 2.5 mg, that’s 2.5 × 1000 = 2500 mcg. This matches the idea that 2.5 mg is the same as 2500 micrograms. The other numbers come from misplacing the decimal or using a different conversion: 250 mcg is 0.25 mg, 25 mcg is 0.025 mg, and 25000 mcg is 25 mg. The correct conversion puts 2.5 mg at 2500 mcg.
