About IV Drip Calculator

IV Drip Calculator is a free, fast tool designed to help nurses and healthcare students calculate intravenous fluid flow rates safely and accurately.

Enter the prescribed volume, the infusion duration and the drop factor of your administration set to instantly obtain the drip rate in drops per minute and the infusion speed in mL per hour.

The formulas used are the standard clinical formulas: drops/min = (volume × drop factor) ÷ time in minutes, and mL/h = volume ÷ time in hours.

This tool supports clinical judgment but never replaces it. Always double-check calculations according to your institution's protocols.
