This gravity IV drip rate calculator computes drops per minute (gtt/min) from the volume to infuse, the infusion time, and the IV set's drop factor. Common drop factors are 10, 15, or 20 gtt/mL for macrodrip sets and 60 gtt/mL for microdrip sets. This calculator is for educational/informational purposes only and is not a substitute for professional medical judgment.
How to Use the Drip Rate Calculator
- Enter the total volume to infuse, in milliliters.
- Enter the infusion time and select whether it's in hours or minutes.
- Enter the IV set's drop factor in drops per milliliter (common sets: 10, 15, 20, or 60 gtt/mL).
- Click "Calculate" to see the drip rate in drops per minute and the equivalent mL/hr rate.
Frequently Asked Questions
Drip Rate (gtt/min) = Volume (mL) x Drop Factor (gtt/mL) / Time (min). If you enter the time in hours, it's converted to minutes first.
The drop factor is the number of drops per milliliter delivered by a specific IV tubing set, printed on the tubing packaging. Macrodrip sets are typically 10, 15, or 20 gtt/mL; microdrip sets are 60 gtt/mL.
