Searching for "volume of a drop of water from an eyedropper", I ran across this answer on Quora:

It depends on the size of the dispensing tip, but generally for a Pasteur pipette it is about 1/20'th of a mL. That is on Earth, at or near sea level.

(Incidentally, other values from other sources put it at 1/17 or 1/18 mL. It will probably be somewhat dependent on the shape of the dropper tip and material.)

Assuming we are "indoors" at standard temperature and pressure, how would the volume of a drop of water vary with surface gravity?

Limits:

• Experiments in space suggest that in microgravity water will likely remain stuck and creep up your arm, so if you call that a drop, the volume could be infinite. (And with you in the center of it! Wringing out Water on the ISS - for Science!)
• At extremely high gravity it may be possible that the water is simply pulled out of the dropper by overwhelming surface tension effects.

But if one were doing this on Mars, or the Moon, or on a hypothetical 2g surface gravity body, how would the volume of a drop of water from a dropper compare to that on Earth? How would it scale with the magnitude of gravity?
