The complete formula for converting grams (g) to milligrams (mg). See the formula, how it works, and worked examples below.

  3. Result: 1 g = 1,000 mg

5 g to mg

  1. Start with 5 g
  2. Multiply by 1,000: 5 × 1,000 = 5,000
  3. Result: 5 g = 5,000 mg

10 g to mg

  1. Start with 10 g
  2. Multiply by 1,000: 10 × 1,000 = 10,000
