Meq/L to Mg/L Conversion Formula

The following formula is used to convert milliequivalents per liter (meq/L) to milligrams per liter (mg/L).

mg/L = meq/L * (Molar Mass / Valence)

Variables:

  • mg/L is the concentration in milligrams per liter
  • meq/L is the concentration in milliequivalents per liter
  • Molar Mass is the molar mass of the substance in milligrams per millimole (mg/mmol)
  • Valence is the valence of the ion

To convert meq/L to mg/L, multiply the concentration in meq/L by the molar mass of the substance and then divide by the valence of the ion.

What is Meq/L?

Milliequivalents per liter (meq/L) is a unit of concentration often used in chemistry and medicine to express the amount of a substance in a solution. It takes into account the chemical valence of the ions present in the solution, providing a more accurate measure of the reactive capacity of the ions than weight alone.

How to Calculate Mg/L from Meq/L?

The following steps outline how to convert the concentration from meq/L to mg/L.


  1. First, determine the concentration in milliequivalents per liter (meq/L).
  2. Next, determine the molar mass of the substance in milligrams per millimole (mg/mmol).
  3. Next, determine the valence of the ion.
  4. Use the formula mg/L = meq/L * (Molar Mass / Valence) to calculate the concentration in mg/L.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem:

Use the following variables as an example problem to test your knowledge.

Concentration in meq/L = 5 meq/L

Molar Mass of the substance = 24.305 mg/mmol (Magnesium)

Valence of the ion = 2 (Magnesium)
