About these units
Barrel (UK) (bbl (UK))
The UK barrel also varies by context but is commonly set at 36 imperial gallons, or about 163.66 liters. Used in British breweries, distilleries, and older trade systems, the UK barrel historically held ale, beer, and spirits. Barrel sizes were not only a reflection of trade standardization but also taxation. Governments often taxed based on container size, prompting industries to standardize capacities for legal and economic stability. Though less prevalent today due to metrication, the UK barrel remains in use in traditional breweries and historical references. It is an enduring symbol of Britain's long brewing heritage and the complex history of imperial trade.
Drop (drop)
The drop is one of the oldest fluid measures and originally referred simply to the amount of liquid that naturally forms at the end of a dripping vessel. Because drop size depends on viscosity, surface tension, temperature, and orifice size, early medicine found drops inconsistent and unreliable. Modern medicine and chemistry sometimes define a drop as 0.05 mL, but this is only a convention used for standardized droppers—real drops can vary significantly. Despite its imprecision, the drop survives in everyday language, aromatherapy, essential oils, and household instructions ("add a few drops"). It exemplifies humanity's earliest attempts to quantify small volumes before scientific instrumentation enabled precise micro-measurement.
