How many milligrams are in 250 micrograms?

• A. 0.25 mg
• B. 2.5 mg
• C. 0.025 mg
• D. 1 mg

Answer: (A)

Converting micrograms to milligrams requires knowing that 1 milligram equals 1000 micrograms. To switch from micrograms to milligrams, divide by 1000. So 250 micrograms becomes 250 ÷ 1000 = 0.25 milligrams. Think of it as: 1000 micrograms = 1 milligram, so 250 micrograms is a quarter of a milligram. The other nearby values would be 2.5 mg (2500 mcg), 0.025 mg (25 mcg), or 1 mg (1000 mcg), which don’t match 250 mcg.
