How do you measure the volume of one drop of water?

To measure a drop of water you should get a measuring cylender. Say you put 100 drops to make the results more accurate. Lets say 100 drops of water in a measuring cylender would show 200cm^3 . So to find the volume of 1 drop of water instead of 100 you would divide 200 by 100 which would give you 2cm^3 for 1 drop of water
