Drops Per Minute Calculator
Calculate IV drops per minute and drip rate from infusion volume, time, and drop factor calibration.
Drops Per Minute in IV Therapy
Drops per minute (gtt/min) controls manual IV infusion rate when an electronic pump is unavailable. It depends on total volume, infusion time, and tubing drop factor. See also the Drip Rate Calculator for weight-based dosing workflows.
Formula
Drops per minute equals volume in milliliters multiplied by drop factor, divided by infusion time in minutes. Drip rate in mL/h equals drops per minute times 60 divided by drop factor.
Drop Factor Guide
Microdrip sets deliver 60 drops per milliliter and are common in pediatrics. Macrodrip sets typically deliver 10, 15, or 20 drops per milliliter. Always use the factor printed on your IV set packaging.
Frequently Asked Questions
What is the drops per minute formula?
gtt/min = (Volume mL × Drop factor) ÷ Time in minutes.
How do I find drop factor?
Check the IV tubing package; it lists gtt/mL for that set.
What is microdrip tubing?
Microdrip tubing delivers 60 drops per milliliter for precise small-volume infusions.
Why is infusion rate accuracy important?
Too fast or too slow delivery can cause electrolyte shifts, fluid overload, or ineffective therapy.
