There is around 15 to 20 drops in one ML. The liquid viscosity will change this answer.
You may consider that there is 80 to 100 drops in a 5ml bottle.
1mL is 20 drops.
120 drops. 20 drops / mL.
There are approximately 240 drops in 10 ml. Therefore 2.5 ml contains about 60 drops.
~60 drops solution: 20 drops/mL * 3 mL = 60 drops
20 drops per mL, therefore 20drops/mL x 10 mL = 200 drops.
50*10 = 500 drops.
16mL is 320 drops.
8mL is 160 drops.
There are approximately 15 macro drops in 1 ml.
Approximately 16 drops is equal to 0.8 ml.
20 drops is 1mL
16 drops of water or any water soluble substance makes 1 ml
