How to convert mEq to mg?

To convert milliequivalents (mEq) to milligrams (mg), you need to know the equivalent weight of the substance.

The equivalent weight is the molecular weight divided by the valence.

The formula for this mEq to mg:

mg = mEq * Equivalent weight


  • mEq = milliequivalent
  • mg = milligram

For example, if you have sodium chloride (NaCl) and you want to convert 5 mEq to mg.


  • Molecular weight = 58.44 g/mol
  • Valence = 1
  • Equivalent weight = 58.44 / 1 = 58.44

put all values into the formula

Milliequivalent = 5 * 58.44 = 292.2 mEq

So, 5 mEq of sodium chloride is equal to 292.2 mg
