Convert Grams to Milligrams

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

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

Going the other way? Convert mg to g.
