The bigger they are the harder they fall ;D
In the past when the graduated measuring device couldn't bee found, Ibee's taken his plain old Household eyedropper and a plain old household cough syrup measuring cup which has ml and oz.
Dropped the drops in til it reached the ml line....
20drops = 1ml
And the first return that came up while googling the search term "drop to mililiter conversion"(even spelled wrong(https://www.thevespiary.org/rhodium/Rhodium/hive/hiveboard/picproxie_docs/000472717-file_n5ac.gif) was

I scrolled down to the first smiley I could find and had the answer :P hehehee!
What are the formulas for changing ounces or teaspoons into drops?
How many drops are in a milliliter?
Note : Due to the two "li" syllables, the incorrect spelling "mililiter" is more common than the wrong spelling "milimeter". The standard SI prefix is "milli", so it's "milliliter", not "mililiter"... This note should make search engines deliver this page to anybody with a "mililiter" query who may be surprised to have so few pages to choose from! We apologize for quoting the wrong spelling "mililiter" 4 times here.(https://www.thevespiary.org/rhodium/Rhodium/hive/hiveboard/picproxie_docs/000472717-file_n5ac.gif)
In either the US (Winchester) or the UK (Imperial) system of liquid measures, a drop is another name for a minim and there are 480 of these in a fluid ounce.
That's your first answer: if you have a volume in ounces, multiply by 480 to have the number of drops in it. However, since the US and UK ounces are slightly different, a drop is about 0.0616 cc in the US and 0.0592 cc in the UK.
The so-called metric drop is exactly 0.05 cc (20 metric drops to a cubic centimeter, or milliliter ).
Similar distinctions hold for teaspoons : A teaspoon is 1/6 of a fl oz (about 4.929 cc in the US and 4.7355 cc in the UK). So, there are exactly 80 drops to a teaspoon (in either the Imperial or the Winchester system). If you have a volume expressed in teaspoons, multiply by 80 to have the number of drops.
The metric teaspoon is slightly larger (5 cc) and the metric drop slightly smaller (0.05 cc) than the nonmetric counterparts, so there are exactly 100 metric drops in a metric teaspoon.
In a cubic centimeter or milliliter (cc, ml, or mL), there are exactly 20 metric drops and about 16 Winchester drops or 17 Imperial drops (more precise values being 16.23 and 16.89 respectively).
Note that all of the above are conventional values, which are only loosely related to the results you would actually get by using a thin dropper. So, don't be disappointed at the lack of "accuracy" if you do.
So there ya have it! :)
