Tips & common mistakes

Quick tips

  • 1 mg = 1/1000 g = 1,000,000 µg. Always check which prefix the label uses.
  • Read medication labels carefully — confusing mg and µg can be a 1000× dosing error.
  • Nutrition labels list minerals in mg and vitamins (A, D, K) in µg.

Avoid these

  • Reading 500 mg as 500 g on a medicine bottle — a potentially fatal 1000× error.
  • Confusing mg (milligram) with mg/kg (dose per kilogram of body weight).
  • Mixing up mg and µg — µg is 1000× smaller.
