Meq/L to Mg/Dl Conversion Formula

The following formula is used to convert a concentration from meq/L to mg/dL.

mg / dL = (meq / L * Molecular Weight) / (Valence * 10)

Variables:

  • meq/L is the concentration in milliequivalents per liter
  • Molecular Weight is the molecular weight of the substance (g/mol)
  • Valence is the valence number of the substance
  • mg/dL is the concentration in milligrams per deciliter

To convert meq/L to mg/dL, multiply the concentration in meq/L by the molecular weight, and then divide by the product of the valence and 10.

* Rounded to 3 decimals. Assumes Calcium (MW 40.078 g/mol, valence = 2). Conversion: 1 mEq/L ≈ 2.0039 mg/dL; mg/dL = mEq/L × MW / (z × 10).

What is Meq/L?

Meq/L (milliequivalents per liter) 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 substance’s valence, or charge, providing a more accurate measure of the substance’s chemical combining power.

How to Calculate Mg/Dl from Meq/L?

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

  1. First, determine the concentration in meq/L.
  2. Next, determine the molecular weight of the substance (g/mol).
  3. Next, determine the valence number of the substance.
  4. Use the formula to calculate the concentration in mg/dL.
  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 (meq/L) = 4 meq/L

Molecular Weight (g/mol) = 40 g/mol (e.g., for sodium)

Valence = 1 (e.g., for sodium)
