WIKIPEDIA

The dram (alternative British spelling drachm; apothecary symbol ʒ; abbreviatted dr)[1][2]:C-6–C-7[3] was originally both a coin and a weight in ancient Greece.[4] It refers to a unit of mass in the avoirdupois system, and both a unit of mass and a unit of volume in the apothecaries' system.[2] The unit of volume is more correctly called a fluid dram, fluid drachm, fluidram or fluidrachm (abbreviated fl dr, ƒ 3, or fʒ)

The Attic Greek drachma was a weight of 6 obols, ¹⁄₁₀₀ Greek mina, or about 4.37 grams.[8]

• The Roman drachma was a weight of ¹⁄₉₆ Roman pounds, or about 3.41 grams.[9][10]
  

The Ottoman dirhem was based on the Sassanian drachm, which was itself based on the Roman dram/drachm.[citation needed] Modern Armenian drams, the currency of the Republic of Armenia, share this origin.[citation needed]
