Milligram to Milliequivalent Converter

Convert milligrams of a substance to milliequivalents based on its molar mass and valence.

Input Parameters

Calculation Results

Calculation Formula

Milliequivalents (meq) = (Mass (mg) / 1000) × Valence / Molar Mass

Where:
Mass (mg): Mass of the substance in milligrams
Valence: Charge or oxidation state of the ion
Molar Mass: Molar mass of the substance in g/mol

Result

Milliequivalents (meq): 0.00

Milligram to Milliequivalent Converter Calculator Usage Guide

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. Enter the molar mass of the substance in grams per mole (g/mol).
  3. Enter 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).

Working Principle

The Milligram to Milliequivalent Converter uses the following formula to perform the conversion:

meq = (mg / 1000) × valence / molarMass

Where:
- mg is the mass of the substance in milligrams
- 1000 converts milligrams to grams
- valence is the charge or oxidation state of the ion
- molarMass is the molar mass of the substance in g/mol

Example

Let's say 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:
meq = (500 mg / 1000) × 1 / 58.44 g/mol
meq = 0.5 g × 1 / 58.44 g/mol
meq = 0.0086 meq

Applications

This calculator is commonly used in chemistry and medicine to convert between mass and equivalent weight of substances. It's particularly useful for calculating dosages in pharmaceuticals, determining the concentration of ions in solutions, and performing stoichiometric calculations.
