Meq vs. Mmol: Know the Difference
By Shumaila Saeed || Published on February 5, 2024
Meq (Milliequivalents) is a unit measuring the amount of a substance based on its chemical activity or ion exchange capacity. Mmol (Millimoles) is a unit measuring the amount of a substance based on its molecular count regardless of its chemical activity.
Key Differences
Meq represents the chemical activity of ions in a solution, considering charge and valence, while Mmol measures the actual number of molecules or ions, independent of their chemical properties.
