About these units
Milliliter (mL)
A milliliter, defined as 1/1,000 of a liter or precisely 1 cubic centimeter, is a small but enormously significant volume unit in cooking, medicine, pharmacy, and laboratory science. Medical syringes, dosing spoons, and IV solutions rely heavily on milliliter accuracy. In laboratories, mL measurements are routine for preparing reagents, dilutions, and biological media. Because 1 mL = 1 cm³, many devices use either notation interchangeably depending on context. Despite its small size, the milliliter is commonly used in daily life as well—perfume bottles, beverage labels, and household cleaners often list contents in milliliters. Its precision and simplicity make the milliliter one of the world's most practical measurement 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 Though less prevalent today due to metrication, the UK barrel remains in use in traditional breweries and historical references.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.
