What is the Pint?

The pint equals exactly one half of a US quart (0.473176473 liters) in the United States and 0.568261 liters in the United Kingdom (the imperial pint, 20% larger than the US pint). The British pint is iconic in pub culture — beer and cider are served in imperial pints in UK pubs, and the imperial pint glass is a regulated measure required by law. In the United States, milk is commonly sold by the pint (often as half-quart cartons), and ice cream containers are often pints (16 fl oz US). The pint relates to the gallon (8 pt = 1 gal), the quart (2 pt = 1 qt), the cup (2 cups = 1 US pt), and the fluid ounce (16 fl oz = 1 US pt; 20 fl oz = 1 imperial pt). The discrepancy between US and UK pints reflects the older 1824 imperial reform that the United States did not adopt.

What is the US Gallon?

The US liquid gallon equals exactly 3.785411784 liters and is the standard volume unit for fuel, beverages, milk, and household liquids in the United States. Defined as 231 cubic inches, the US gallon descends from the English wine gallon of 1707, which Britain replaced with the larger imperial gallon in 1824 — a divergence that left the United States with a different gallon than the rest of the English-speaking world. American gas stations price gasoline by the gallon (typical fill-up: 12–15 gallons), milk is sold in half-gallons and gallons, and many beverages come in fluid-ounce subdivisions of the gallon. The US gallon relates to the liter (1 gal ≈ 3.785 L), the quart (4 qt = 1 gal), the pint (8 pt = 1 gal), the cup (16 cups = 1 gal), and the imperial gallon (1 imp gal ≈ 1.201 US gal — about 20% larger).
