mg to mEq potassium converter Calculator
The mg to mEq potassium converter Calculator estimates milliequivalents (mEq) based on the milligram amount and specific potassium compound selected. This tool helps healthcare providers and patients ensure accurate dosage conversions and safe electrolyte management. Whether you are calculating IV fluid concentrations, reviewing supplement labels, or performing nutritional analysis, this tool provides instant clarity.
How Milliequivalents (mEq) Is Calculated
Milliequivalents (mEq) measure the chemical combining power of a substance, which reflects its physiological activity better than weight alone. This calculation uses the molecular weight specific to the potassium compound you are using.
mEq = mg ÷ Molecular Weight
Where:
- mEq = milliequivalents
- mg = milligrams of the compound
- Molecular Weight = Varies by compound (e.g., 74.5 for KCl)
- Identify the total milligrams of the potassium compound.
- Select the correct molecular weight based on the compound type (Chloride, Citrate, etc.).
- Divide the milligrams by the molecular weight.
This step is vital because different salts contain different amounts of actual potassium ions. Using the correct molecular weight ensures the result reflects the active electrolytes available for the body. This method adheres to standard pharmacological conversion practices for precise medical dosing.
What Your Milliequivalents (mEq) Means
This number represents the active chemical potential of the potassium in your specific sample. It tells healthcare professionals exactly how much electrolyte is available to react in the body, which is critical for heart and nerve function.
Medical Dosage: Common prescription doses often range from 20 mEq to 40 mEq per dose to treat hypokalemia (low potassium). Knowing this helps verify that a prescribed pill matches the required strength.
Nutritional Analysis: While food labels list milligrams, understanding mEq helps clinicians compare dietary intake directly with medical supplements. For reference, a banana has about 10 mEq of potassium.
IV Safety: IV solutions are strictly measured in mEq to prevent heart complications. Peripheral IV lines usually limit potassium to 10 mEq per 100mL to avoid irritation.

Always double-check whether your result refers to the compound or elemental potassium. If your results seem off compared to daily recommended values, verify you selected the correct compound type.
