About Fluid Drams
A fluid dram (fl dr, also 'drachm') = 1/8 fl oz ≈ 3.697 mL. Used by apothecaries for precise medicinal compounding; a fluid dram divided into 60 minims. Largely superseded by millilitres but still appears in traditional compounding recipes, older US pharmacopeias, and historical medical literature. 1 fl dr ≈ 3.697 mL.
About Oil Barrels
An oil barrel (bbl) = exactly 42 US gallons ≈ 158.99 L - established by the Pennsylvania oil industry in the 1860s and now the global petroleum standard. Global oil production, OPEC quotas, and crude spot prices are all quoted in barrels or Mb/d (millions of barrels per day); world consumption ~100 Mb/d in 2024. 'Bbl' derives from the 'blue barrel' mark on petroleum containers. 1 bbl = 42 US gal ≈ 159 L.
