Convert Milligrams to Grams

Milligrams → Grams
mg × 0.001 = g g × 1000 = mg

To convert milligrams (mg) to grams (g), multiply the milligrams value by 0.001. 1 mg = 0.001 g, and 1 g = 1000 mg. The conversion is a linear scaling with no offset, so the same factor applies to any value.

Going the other way? Convert g to mg.
