mEq ↔ mg Electrolyte Converter
Convert electrolyte doses between milliequivalents and milligrams — potassium, sodium, calcium and more.
mEq accounts for electrical charge: divalent ions (Ca²⁺, Mg²⁺) pack 2 charges per molecule, so the molar-mass-over-valence math matters. Anchors: 20 mEq KCl = 1,491 mg = a common potassium supplement; 1 g KCl = 13.4 mEq. Crucial distinction: 'mEq of potassium' vs 'mEq of KCl salt' differ — always confirm whether the order means the ion or the compound.
