Potassium Correction Calculator

Current Potassium Level (mmol/L)Body Weight (kg)Requirement Factor (mmol/kg/day)

8.12 g KCl

Deficit: 48.0 mmol · Requirement: 60.0 mmol · Total: 108.0 mmol

≈ 13.5 Slow-K tablets or 16.2 × Mist KCl 5ml

Show formula

Deficit = 0.4 × (4 − K⁺) × BW
Requirement = Factor × BW
Total = Deficit + Requirement
Potassium (g) = Total ÷ 13.3
