What is a Dram and a Stone?
The dram (or drachm) can refer to several units. In the context of common weight conversion (Avoirdupois system), it is a unit of mass equal to 1/16 of an ounce or 1/256 of a pound. This Avoirdupois dram is approximately 1.7718 grams.
The stone (st) is a unit of mass in the British imperial system, defined as exactly 14 avoirdupois pounds. This is equivalent to approximately 6.35 kilograms.

History of the Dram and Stone
The term originates from the Greek drachma coin. It became a unit in multiple historical weight systems (Avoirdupois, Apothecaries', Troy). The Avoirdupois dram was used for general commodities.
The stone has historical roots in trade, where actual stones were used as weights. Its value varied significantly by commodity and region before being standardized at 14 pounds in Britain for general purposes.
