How many drops (gtt) are in 1 milliliter (ml)?

Explanation:
Drops per milliliter depend on the drip factor of the IV administration set. For a standard macrodrip set used in veterinary practice, the drop factor is 20 drops per milliliter, so 1 mL contains 20 drops (1 mL × 20 gtt/mL = 20 gtt). Keep in mind that different sets exist—some macrodrips use 10 or 15 gtt/mL, and microdrips use around 60 gtt/mL—so always check the exact drip factor on the tubing to convert accurately.
