About this calculator

The dram most commonly meant here is the avoirdupois dram, 1/16 of an avoirdupois ounce, equal to exactly 1.7718 grams; the apothecaries' dram (used historically for medicine dosing) is a different, slightly larger unit at about 3.888 grams, so context matters when converting.

The unit survives mainly in older pharmacy prescriptions and compounding recipes, some US recipe writing, and shooting-sports contexts (gunpowder charges are still sometimes specified in drams), so pharmacists, historians, and hobbyists occasionally need to translate a dram figure into the grams modern scales actually display.
