Meq/L to Mg/L Calculator

Input three known values—milliequivalents per liter (meq/L), molar mass of the substance, valence of the ion, or concentration in mg/L—to calculate the missing parameter.

The Meq/L to Mg/L Calculator simplifies the conversion between milliequivalents per liter (meq/L) and milligrams per liter (mg/L). This tool is invaluable in scientific, medical, and chemical fields, where accurate ionic or molecular concentration measurements are essential. By providing three parameters, the fourth can be calculated effortlessly, making it an essential resource for precise and efficient calculations.

Conversion Formulas

Concentration (mg/L): $\text{mg/L} = \frac{\text{meq/L} \times \text{Molar Mass}}{\text{Valence}}$
Milliequivalents per Liter (meq/L): $\text{meq/L} = \frac{\text{mg/L} \times \text{Valence}}{\text{Molar Mass}}$
Molar Mass: $\text{Molar Mass} = \frac{\text{mg/L} \times \text{Valence}}{\text{meq/L}}$
Valence: $\text{Valence} = \frac{\text{meq/L} \times \text{Molar Mass}}{\text{mg/L}}$

Variable	Description	Unit Example
$\text{meq/L}$	Milliequivalents per liter	meq/L, eq/L
$\text{Molar Mass}$	Weight of one mole of the substance	mg/mmol, g/mol
$\text{Valence}$	Ionic charge or combining power of the ion	Unitless
$\text{mg/L}$	Concentration in milligrams per liter	mg/L, g/L

Solved Calculations

Example 1:

Input Parameters	Value
$\text{meq/L}$	5
$\text{Molar Mass}$	40.08 mg/mmol
$\text{Valence}$	2
$\text{mg/L}$	$\frac{5 \times 40.08}{2} = 100.20 \, \text$

Example 2:

Input Parameters	Value
$\text{mg/L}$	200
$\text{Molar Mass}$	58.44 mg/mmol
$\text{Valence}$	1
$\text{meq/L}$	$\frac{200 \times 1}{58.44} = 3.42 \, \t$
