Milligram to Milliequivalent Converter

Convert milligrams (mg) to milliequivalents (mEq) based on molar mass and valence of the substance.

Input Parameters

Calculation Results

Calculation Formula

mEq = (mg × valence) / molarMass

Where:
mEq = milliequivalent
mg = mass in milligrams
valence = charge of the ion
molarMass = molar mass in g/mol

Result

--

milliequivalents (mEq)

Learn how to use the Milligram to Milliequivalent Converter calculator and its working principles

How to Use This Calculator

  1. Enter the mass of the substance in milligrams (mg).
  2. Input the molar mass of the substance in grams per mole (g/mol).
  3. Specify the valence (charge) of the ion or substance.
  4. Click the "Calculate" button to convert milligrams to milliequivalents.
  5. The result will be displayed in milliequivalents (mEq).

Understanding Milliequivalents

Milliequivalents (mEq) are a unit of measurement used in chemistry and medicine to express the concentration of a substance based on its charge. It is particularly useful in pharmaceuticals and clinical chemistry for calculating the equivalent dose of charged substances.

Example Calculation

Suppose you have 500 mg of sodium chloride (NaCl) and want to convert it to milliequivalents. The molar mass of NaCl is approximately 58.44 g/mol, and sodium has a valence of +1.

Calculation: (500 mg × 1) / 58.44 g/mol = 8.56 mEq

Applications

This calculator is commonly used in medical settings to calculate the amount of a substance needed for infusion based on patient weight, or to determine the correct dosage of medications that are based on ion concentration rather than mass.
