A dram is a unit of mass that has been used since the times of Ancient Greece. It originated from the name of the Greek coin, a drachma, and is linked to the weight of this coin in the early epochs. There was also the Roman dram, which was a little lighter (roughly 3.41 grams) from the Greek dram (about 4.37 grams)1
However, in modern times, a dram is used as a unit of volume equaling 1/8th ounce or 3.7 milliliters12
. Therefore, 5/8 dram would be equal to 1.85 milliliters
for a Screw on Funnel.
