How to Convert Cubic Inch to Pint Manually
Step by StepConverting cubic inches to pints is straightforward: multiply by the conversion factor. Follow these three steps to do it by hand or in your head.
- 1Take your value in cubic inchesStart with the number of cubic inches (in³) you want to convert.
- 2Multiply by 0.034632The conversion factor from in³ to pt is 0.034632. Multiply your value by this number.
- 3Read the result in pintsThe result is your value in pints (pt).
Formula
Multiply the value in cubic inches by 0.034632. For the reverse direction, multiply by 28.875.
pt = in³ × 0.034632in³ = pt × 28.875Tips
Use these in everyday conversions- 1 in³ = 16.387 cm³ exactly.
- To convert cubic inches to litres, divide by 61.02.
- US automotive ads today quote both cu in and L for classic cars.
Common Mistakes
Avoid these- Confusing in³ with in² or linear inches.
- Using 16 instead of 16.387 on precision machining.
- Assuming modern European engines are marked in cu in — they are always in L or cc.
About Cubic Inch and Pint
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.
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.
