  • dr
    Dram (3.888 grams)
    The apothecaries' system or apothecaries' weights and measures is a historical system of mass and volume units that were used by physicians and apothecaries for medical recipes, and also sometimes by scientists. Dram, unit of weight in the apothecaries’ and avoirdupois systems. An apothecaries’ dram contains 3 scruples (3.888 grams) of 20 grains each and is equal to one-eighth apothecaries’ ounce of 480 grains.
  • dwt
    Pennyweight (1.5552 gram)
    The pennyweight symbol is dwt. There are 24 grains in 1 dwt, and 20 dwt in one troy ounce. Because there were 12 troy ounces in the old troy pound, there would have been 240 pennyweights to the pound—the basis of the fact that the old British pound sterling of currency contained 240 pence. (However, prior to 1526, English pound sterling was based on the tower pound, which is 15⁄16 of a troy pound.) The d in dwt stands for denarius, the ancient Roman coin, referred to in the New Testament, that equates loosely to a penny. The symbol d for penny can be recognized in the notation for British pre-decimal pennies, in which pounds, shillings, and pence were indicated using the symbols £, s, and d, respectively. For example, £6 11s 8d indicated six pounds, eleven shillings, and eight pence.
