Health
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.

Tool usage guide
The Medication Dose/Rate Calculator converts between a prescribed medication dose and an infusion-pump rate in mL/hr. It supports weight-based units such as mcg/kg/min, mg/kg/hr, and units/kg/hr, plus flat dosing in units/hr. This tool is not medical advice, and high-alert infusions require an independent double-check.
Background
A dopamine bag contains 400 mg in 250 mL. The prescribed dose is 5 mcg/kg/min for a 70 kg patient.
Problem
Convert the prescribed weight-based dose into a pump rate in mL/hr.
How to use
Select Dose → Rate, choose mcg/kg/min and mg/mL, then enter 400 for drug amount, 250 mL for volume, 70 kg for weight, and 5 for dose.
Decimal places: 2Outcome
The calculator reports a rate of 13.13 mL/hr.
Background
A heparin bag contains 25,000 units in 250 mL, and the infusion pump is running at 15 mL/hr.
Problem
Confirm the delivered flat dose in units/hr without using patient weight.
How to use
Select Rate → Dose, choose units/hr and units/mL, then enter 25,000 for drug amount, 250 mL for volume, and 15 mL/hr for the pump rate.
It converts between a medication dose and an infusion-pump rate in mL/hr.
The calculator supports mcg/kg/min, mg/kg/hr, units/kg/hr, and units/hr.
Weight is required for weight-based units and is ignored for flat dosing in units/hr.
You can enter concentrations in mg/mL, mcg/mL, or units/mL.
No. Confirm the result against the prescription, medication label, and local protocol. High-alert infusions require an independent double-check.
Decimal places: 2Outcome
The calculator reports a delivered dose of 1,500 units/hr.
