This IV infusion rate calculator converts a mcg/kg/min drug order into a dose per minute and a pump rate in mL/hr, based on patient weight and drug concentration. This calculator is for educational/informational purposes only and is not a substitute for professional medical judgment.
How to Use the MCG Minute Calculator
- Enter the patient's weight in kilograms.
- Enter the ordered dose in micrograms per kilogram per minute (mcg/kg/min).
- Enter the drug's concentration in micrograms per milliliter (mcg/mL) — for example, 400 mg in 250 mL works out to 1600 mcg/mL.
- Click "Calculate" to see the dose per minute and the pump infusion rate in mL/hr.
Frequently Asked Questions
Dose per minute (mcg/min) = Patient Weight (kg) x Ordered Dose (mcg/kg/min).
Infusion Rate (mL/hr) = Dose per minute (mcg/min) x 60 / Concentration (mcg/mL). Multiplying by 60 converts the per-minute dose to a per-hour dose before dividing by concentration.
