(drachm; Russian drakhma, from Greek drachme).

(1) A unit in the now outmoded system of apothecaries’ weights. An apothecaries’ dram was one-eighth of an ounce and contained three scruples; the Russian apothecaries’ dram was the equivalent of 3.732 g. In the English system of measurement an apothecaries’ dram equaled 3.888 g.

(2) A fluidram, a measure of displacement used in the USA, equal to 3.6966 milliliters.

(3) In the avoirdupois system, a measure of weight equaling one-sixteenth of an ounce, 1.772 g.
