How to convert milligrams to grams
Milligrams and grams are metric mass units differing by a factor of 1,000. The prefix 'milli-' means one-thousandth, so 1 gram = 1,000 milligrams. Milligrams are standard for medication dosages, nutritional micro-nutrients, and laboratory measurements.
Divide milligrams by 1,000 to get grams. Formula: g = mg ÷ 1,000. A 500 mg vitamin C tablet is 0.5 g. A 250 mg aspirin dose is 0.25 g.
Pharmacists, dietitians, and chemists convert between these units daily. Nutrition labels list sodium in milligrams while total serving weight may be in grams. A daily limit of 2,300 mg sodium equals 2.3 g.
This is a simple decimal shift: 1,000 mg = 1 g, 500 mg = 0.5 g, 50 mg = 0.05 g. Move the decimal three places left to convert mg to g.
