How the conversion works

Formula
mg = g × 1,000
Example
10 g → 10 × 1,000 = 10,000 mg

Multiply the gram figure by 1,000 to get milligram. 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 mg = 0.001 g — see milligram to gram.
