Also spelled «drachm»

1 greek drachm = 4.37 g
1 Roman drachm = 3.41 g
As a mass unit:
Now, it's 1/16 ounce, or 875/32 grains or 1.771 845 195 312 5 g

BUT, for an apothecair, it's double that, or 3 scrupules.

As a volume unit:
3.696691 ml (USA) or 3.551632 ml (Commonhealth and Ireland)

In a bar, it's 330 ml of whisky...
