About these units

Imperial Pint (pt (UK))

Imperial (British)Current unit

Exactly 568.26125 mL (20 imperial fluid ounces). The pint of beer and milk in the UK and Ireland.

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.

1 imperial pint = 0.56826125 liters (exactly).

Metric Cup (cup)

Cooking & barCurrent unit

Exactly 250 mL. The cup used in Australia, New Zealand and most Commonwealth recipes.

A metric cup is a cup tamed by decimal thinking. Australia, Canada, New Zealand and some other former British colonies that metricated use a round 250 milliliters, exactly a quarter of a liter. Canada's older cup had been eight imperial fluid ounces, about 227.3 mL, so the metric version is noticeably larger, and Canadian recipes now usually use the 250 mL cup.

The metric cup is not an SI unit, only a practical convention, and it differs from the US cups in useful ways. It is about 6 percent larger than the US customary cup at 236.6 mL and about 4 percent larger than the 240 mL US label cup. Its arithmetic is simple: four cups make a liter, and a cup holds 50 metric teaspoons or 16 and two thirds tablespoons of 15 mL. Many recipes outside the US skip cups entirely and give dry ingredients in grams, because volume is a rough proxy for flour.

1 metric cup = 0.25 liters (exactly).
