Drops Per Minute Calculator
Result
Drops Per Minute Calculator Calculate the IV drip rate in drops per minute for gravity infusion based on volume, time, and drop factor. — free online calculator.
Formula
- Drops Per Minute Calculator calculates its result from Total Volume, Infusion Time, Drop Factor (gtt/mL). It uses the formula gtt/min = (Volume (mL) × Drop Factor) ÷ (Time (hr) × 60). Change any input to recalculate the result instantly. This is an informational calculation and is not medical advice.
- The main inputs are Total Volume, Infusion Time, Drop Factor. Enter them in the units and format shown in the calculator.
- Use the measurement units shown beside each field. The result is an estimate and should be interpreted in context.
- Changing any input above recalculates the result with the same calculation engine used by this page.
Example: Drops Per Minute
- Total Volume: 1000
- Infusion Time: 8
- Drop Factor: 20 gtt/mL
Using Total Volume = 1000, Infusion Time = 8, Drop Factor (gtt/mL) = 20, the calculated result is 41.6666666667.
