Medication Dose/Rate Calculator (mg/kg/hr etc.)

Convert bidirectionally between a prescribed clinical dose and an infusion-pump rate (mL/hr). Supports weight-based (mcg/kg/min, mg/kg/hr, units/kg/hr) and flat (units/hr) dosing. Two directions: Dose → Rate and Rate → Dose. ALL high-alert infusions require independent double-checking (ISMP). Derived from Macklin 2011, ISMP, Royal Marsden 9th ed. 2015, and MDCalc. Not medical advice.
