A drop is defined as 1/60th of a teaspoon. See that attached link.

Therefore there are 60 drops per teaspoon. There are 3 teaspoons per tablespoon, so;

180 drops per tablespoon. There are 16 tablespoons per cup so;

2880 drops per cups;

There are 4 cups per quart, so

11520 drops per quart;

and 4 quart per gallon, so;

46080 drops per gallon, and finally there are 3.785 liters per gallon so there are ---

12,174.4 drops in a liter.

In a really stupid site without hyperlinks

http://www.medilexicon.com/medicaldictionary.php?t...

a drop of water is described as equal to a minim

which is equal to a 1/60th of a fluidrachim

which is described as 1/8th of a fluidounce

or a teaspoonful or 3.70 ml in the US (less in UK)

so 1/60 x 3.70 = 0.061667 ml

which yields 16.27 drops per ml

You know a milliliter (mL) is one cubic centimeter (cc) of volume. I've heard that it takes about 20 drops to fill one up. So, that would mean 20 000 per liter.

1 ... if the drop is a litre in size

2 ... if each drop is half a litre...

2,000 ... if each drop is 0.5cc

[get the picture...?]

it depends on the size of the drop... "drop" is not a precise measure of volume so your question is impossible to answer.
