US Pint (pt)
The US pint, symbolized as pt, is equal to 1/8 of a US gallon, or approximately 473 milliliters. Derived from British units, it became standardized in the US after independence. Pints are commonly used for beverages like beer and milk in the United States. Unlike the British imperial pint (568 mL), the US pint is smaller, creating distinctions in international trade and cultural habits. Despite metrication globally, the pint remains a familiar and enduring unit of measurement in everyday American life.
Imperial Gallon (imp gal)
The imperial gallon, shown as imp gal, is a British unit equal to 4.54609 liters. It came from English wine and drink measures in the 1800s and became official in 1824. The imperial gallon was used throughout the British Empire and is still used in the UK and some other countries for fuel and beverages. The liter is now used almost everywhere, but the imperial gallon still exists because of custom and local use.
