About the imperial pint

The imperial pint derives from Parliament's 1824 decision to replace Britain's assorted gallons with one defined by ten pounds of water at 62 degrees Fahrenheit. A pint is one eighth of that gallon and holds 20 imperial fluid ounces, or exactly 568.26125 milliliters. The word reached English from French pinte, which in modern French now means half a liter, while Canadian French uses it for the imperial quart.

That pint is about 20 percent larger than the US liquid pint of 473 mL, so a pint in Dublin or London buys noticeably more beer than one in Chicago. When Britain metricated, the pint was kept for draught beer and cider and for milk in returnable bottles, and draught beer has to be served in measured, stamped glasses. Culturally the pint is more than a measure: it is shorthand for a night at the pub.
