- UK pint = 20 UK fl oz; US pint = 16 US fl oz.
- When reading a pint figure, always note country context.
Common Mistakes
Avoid these- Assuming a US pint equals a UK pint — 20% off.

About Pint and Cubic Inch
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.
- UK draft beer (half-pint and pint glasses)
- British doorstep milk delivery
- US ice-cream and ale packaging
A UK pub pint is 568 ml by law. A US pint of Ben & Jerry's ice cream is 473 ml. UK milk bottles are often pints.
What is the Cubic Inch?
The cubic inch equals exactly 16.387064 cubic centimeters and is the traditional American unit for engine displacement and small-volume manufacturing measurements. Classic American muscle cars were famously identified by their cubic-inch engine size: the Ford 'Boss 429' had a 429-cubic-inch (7.0-liter) V8, and the Chevrolet 'Big Block 454' was 7.4 liters. Modern American automakers have transitioned mostly to liter-based naming (e.g., 'Hemi 5.7'), but the cubic inch persists in vintage car culture and aviation engines. It is also used for printer-paper coverage and industrial tolerances. The cubic inch relates to the cubic foot (1,728 in³ = 1 ft³), the cubic centimeter (1 in³ ≈ 16.39 cm³), the milliliter (1 in³ ≈ 16.39 mL), and the US fluid ounce (1 fl oz ≈ 1.805 in³).

- Firearms chamber and cartridge specs
- Some US machining and mould design
350 cu in V8 = 5.7 L engine. 302 cu in Ford V8 = 4.9 L. Modern specs typically give litres.
