Calculates IV Drip Rate Calculator using the formula verified against the cited source.
What your result means
An estimate from the inputs you enter, within the scope stated below — not advice.
Formula
Drip rate (gtt/min) = (volume(mL) × drop factor) ÷ time(min)
The step-by-step working for your own numbers appears with the result above and in the PDF report.

Symbols and assumptions
- Inputs
- The values entered in the fields above
- • Gravity infusion calculation: drops/min=(prescribed volume mL×actual tubing drop factor drops/mL)/prescribed duration minutes. Pump mL/hour=volume mL/duration hours.

- • Require positive time/drop factor and explicit conversion from hours if used. Round gravity drops to the locally approved whole-drop convention; do not assume tubing factor from its label category. Arithmetic does not establish the prescribed volume or clinically appropriate rate.
Important limitation
This is an educational estimate based only on the values and formula shown. Verify current rates, rules, units, and professional standards before relying on the result. It is not personalized financial or investment advice.
