    Whats the size of the drop?. joking
    I would better use ml that drops.
    1 U.S teaspoon measurement is ~4.9 ml and 1 U.K teaspoon is ~5.9 ml

    If you are using it for measurement for quantity of fertilizer, I would highly recommend a TDS meter for dosage.

    Every conversion I have ever seen is 76 drops/US teaspoon.

    There are a variety of 'standard' conversions out there, but take them all with some skepticism if you are counting drops to get to a volume. Drop size depends on the density, surface tension and viscosity of the solution - so pure water is not the same as a fertilizer concentrate, or vanilla extract, or oil, or milk, or whatever. And it depends on the aperture and material of the dropper, so a fine tip glass dropper doesn't give the same drop size as a wide bore glass dropper or a fine tip plastic dropper. It also depends on gravity, which is not precisely the same at all points and elevations on Earth.

    And, the difference between a US and UK teaspoon has already been mentioned, but even within the US a culinary measure teaspoon (-4.93mL) is different than a nutritional serving teaspoon (5mL).
