The volume of a drop of a given liquid depends on the shape and materials of construction of the drop dispenser. Ethanol interacts differently with glass than plastic, and differently with different kinds of plastic. The size of a droplet is also dependent on the surface area of the point at which the drop forms. Ethanol does not "bead" on plain glass surfaces. Instead it tends to spread out, because it interacts with the surface. On the other hand, ethanol, just like water, will bead on certain inert plastics, due to a lack of interaction with those materials (ie. doesn't "cling" to them). So a PTFE dropper, for example, will form smaller drops than a glass dropper, and a very narrow needle-like dropper tip will form smaller drops than a thick, blunt dropper tip. Based on the selection of one's dropper, the volume of a droplet of ethanol could vary by upwards of 150%.

In Britain a standard serving of liquor is 25 ml. In USA it is usually 18 ml

1mL is 20 drops.
20 drops = 1ml 20 drops = 1cc 1ml = 1cc
20 drops is 1mL
20 drops of water is 1mL
There are approximately 20 drops in 1 ml of normal saline.
For 8lbs, you would need 4 drops because 1 drop is required for every 2lbs. So, with 25 drops equaling 1ml, for 8lbs you would need 0.16ml (4 drops x 1ml / 25 drops).
Drop size may vary, but it takes about 25 drops from an oldfashioned glass eyedropper to provide 1ml. Thus it would take about 3,750 drops to yield `150 ml.
15 gtts (drops) = 1ml 1.5ml --> 15 gtts + (15/2=7.5) = 22.5 drops
It takes about 20 drops of water to equal 1 milliliter.
It depends on the viscosity of the fluid, but the common rule of thumb for liquids is 18-20 drops per ml (20 drops being the accepted conversion rate for pharmacological purposes).
1 milliliter = 20 drops.
