History of pint (UK) [pt (UK)] unit

The pint developed from older English measurement traditions, whose size varied before imperial standardisation. The Imperial pint was established by the British Weights and Measures Act of 1824, defining it as one eighth of an imperial gallon. That gallon was based on the volume of ten pounds of distilled water under specified conditions. The imperial system replaced numerous regional pints, though older wine, ale, and dry pints had different values. After metrication, the UK pint remained legally recognised for draught beer and cider sales.
