How do you calculate drops per minute?
Drops per minute = ml/h × drops per ml of the set ÷ 60. Pick the set and enter any of the three values: the converter works out the other two.

Drip set
Drops per ml are printed on the set's package.
How long does this volume take?
Enter the volume and the rate.
How many drops are in one ml?
One ml has 10, 15 or 20 drops with a standard set and 60 with a microdrip set; the number is printed on the package. With a microdrip set, drops per minute equal ml/h.
How do you convert drops per minute to ml/h?
ml/h = drops per minute × 60 ÷ drops per ml of the set. 25 drops per minute with a 10 drops/ml set is 150 ml/h.
How long does an IV bag take?
Time in hours is the volume in ml ÷ the rate in ml/h. A 500 ml bag at 200 ml/h takes 2 hours 30 minutes.
How do you set a drip rate without a pump?
Count the drops in the chamber for 15 seconds and multiply by 4 to get drops per minute. Or use the converter's seconds per drop and turn the clamp until one drop falls in that time. Check the bag and the rate every 1 to 2 hours (2024 AAHA).
How to calculate drops per minute
- Read on the package how many drops per ml the set gives (10, 15, 20 or 60).
- Multiply ml/h by the drops per ml.
- Divide by 60: the result is drops per minute.
- For seconds per drop, divide 60 by the drops per minute.
The formula is the same in human medicine.
