According to the U.S.G.S. the average size of water droplet from a bathroom or kitchen faucet is about 1/4 of a milliliter (or CC), or 4,000 drops per liter; and about 0.0169 fl oz or 15,140 drops per gallon.

Some science measurements from droppers measure a drop much smaller, at 1/20th of a CC per drop, making the number of drops per gallon much higher.

20 drops/CC X 30 CC/fl oz X 128 fl oz/Gal = 76800drops/gal

In the end, it depends on the size of the drop as to how many drops there are in a gallon. For household leaks, 3-4 drops/CC is much more likely than 20-24 drops/CC that is often cited for scientific purposes.
