Enter the milliequivalents (meq), valence, and atomic or molecular weight into the calculator to convert meq to milligrams (mg).
Meq to Mg Conversion Formula
The formula to convert milliequivalents to milligrams is:
mg = (meq * Atomic/Molecular Weight) / Valence
Variables:
- mg is the mass in milligrams
- meq is the amount in milliequivalents
- Atomic/Molecular Weight is the atomic or molecular weight in mg/mmol
- Valence is the valence of the substance
To convert meq to mg, multiply the milliequivalents by the atomic or molecular weight and then divide by the valence of the substance.
What is a Milliequivalent?
A milliequivalent (meq) is a unit of measure that reflects the amount of a substance based on the number of ions or electrons that the substance can supply in a chemical reaction. It is commonly used in chemistry and medicine, particularly in the context of electrolyte concentrations in fluids.
How to Calculate Milligrams from Milliequivalents?
The following steps outline how to calculate milligrams from milliequivalents.
- First, determine the amount in milliequivalents (meq).
- Next, determine the valence of the substance.
- Then, determine the atomic or molecular weight in mg/mmol.
- Use the formula: mg = (meq * Atomic/Molecular Weight) / Valence.
- Finally, calculate the mass in milligrams (mg).
- 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.
Milliequivalents (meq) = 5 meq
Valence = 2
Atomic or Molecular Weight (mg/mmol) = 24.305 (Magnesium)
