About Grams and Milligrams
The gram is the everyday metric unit for small masses, and the milligram — one-thousandth of a gram — is used where precision matters, such as medicine and chemistry. Since "milli" always means ×1,000 when going down a level, gram-to-milligram conversion is a clean decimal shift.
Quick Conversion Tips
No math is really needed: multiply by 1,000 = move the decimal point three places to the right. 2.5 g → 2,500 mg; 0.75 g → 750 mg; 0.05 g → 50 mg. Going back is just as easy — move it three places to the left.
