Enter the mmol and the moles into the Calculator. The calculator will evaluate the Grams from mmol. 

Grams from mmol Formula

G = mmol * mol / 1000


  • G is the Grams from mmol (grams)
  • mmol is the mmol
  • mol is the moles

To calculate Grams from mmol, multiply the mmol by the number of moles, then divide by 1000.
