How to convert
To convert mg to µg, multiply: µg = mg × 1,000
To convert µg to mg, divide: mg = µg ÷ 1,000 (equivalently × 0.001).
Example: 1 mg × 1,000 = 1,000 µg. The factor is derived from the international definition of each unit; results are shown to 4 significant figures.
Frequently asked questions
1 mg = 1,000 µg. The formula is: value in mg × 1,000 = value in µg. Use the converter above to convert any value instantly.
1 µg = 0.001 mg. To convert back, divide the µg value by 1,000 (or multiply by 0.001).
µg = mg × 1,000; conversely mg = µg ÷ 1,000. For example, 1 mg × 1,000 = 1,000 µg. The factor comes from the international definition of the units.
