Work out drops per minute instantly with clear inputs, formula shown and shareable results.
Converts a volume and time into a gravity drip rate for the selected giving set, and shows the equivalent pump rate.
Drops per minute
Drops/min = volume (mL) x drop factor (drops/mL) / time (minutes)
Educational estimate only. Not a substitute for professional clinical judgement, and must not be used to make treatment or dosing decisions.
Count drops for 15 seconds and multiply by four, or use the seconds-per-drop interval for slow rates.
Drop size varies slightly with viscosity, which is why blood sets use 15 drops/mL rather than 20.
