Drops per minute to milliliters per hour
Type a value in gtt/min to get it in mL/h instantly.
375mL/h
That's 3× as fast as a standard infusion, while a rapid infusion is 1.33× faster. A one-liter bag would last about 2.667 hours.
Convert the other way: mL/h to gtt/min
What it means
How fast is it running?
Information only, not clinical guidance. Gravity lines drift as the bag empties and the patient moves, so a counted rate needs rechecking.
The math
How to convert gtt/min to mL/h
The drop factor connects the two: drops/min = mL/h × drops per mL ÷ 60. The figures below use the giving set selected above.
Example: 125 gtt/min = 375 mL/h.
The table below is for Standard adult set (20 drops/mL).
