In science it can mean a drop.
Drop
gtt one drop is " gt " drops are " gtt " a common error is to write " gtts " for drops
1 tsp is equal to 5ml. 1 gtt ( 1 drop) is equal to 0.05 ml....because 20 drops in 1 ml. so 5ml divided by 0.05= 100 gtt or drops. so I think 100 gtt or drops in 1 tsp.
The medical abbreviation 10 gtt means 10 drops. It is commonly used in medication prescriptions to indicate the number of drops to be administered.

gtt means a drop. It is a very small quantity. Generally speaking, there are about 20 drops in 1 mL, which would mean that one drop is 1/20 of a mL or 0.05 mL. That's just an approximation. Exact measurements are impossible without extremely precise measuring instruments. Of course, with more viscous substances this measurement would be different; these approximations generally apply only to water or other aqueous substances.
