How the conversion works
- Formula
- g = mg × 0.001
- Example
- 10 mg → 10 × 0.001 = 0.01 g
Multiply the milligram figure by 0.001 to get gram. Every factor on this site is anchored to the SI base unit for weight & mass, so the same number is used everywhere it appears.
Going the other way, 1 g = 1,000 mg — see gram to milligram.
