➤ Why does a 60 gtt/mL drop factor make mL/hr numerically equal to gtt/min?
A 60 gtt/mL drop factor means one milliliter equals 60 drops. When you multiply mL/hr by 60 then divide by 60 minutes, the factors cancel algebraically. Thus the numeric mL/hr equals the gtt/min value. That property makes microdrip sets convenient for low-rate infusions and simple bedside calculations.
