How to convert millimoles per liter to micromoles per liter

To convert millimoles per liter to micromoles per liter, multiply the number of millimoles per liter by 1000.

Formula

µmol/L = mmol/L × 1000

Examples

  • 5 mmol/L = 5 × 1000 = 5000 µmol/L
  • 25 mmol/L = 25 × 1000 = 25000 µmol/L
  • 100 mmol/L = 100 × 1000 = 100000 µmol/L
