What is a UK fluid ounce?
A UK imperial unit equal to 1/20 of an imperial pint (exactly 28.4130625 ml). Used in the UK and Canada on older recipes, drinks measures and some bottle labels.
What is a cubic inch?
The volume of a cube with 1-inch sides. Used in the US for small mechanical parts and engine displacement.
Who Converts UK Fluid Ounces to Cubic Inches?
UK fluid ounces are used mainly in the UK (pub pints, fuel economy in mpg) and older Canadian recipes, while cubic inches are used mainly in the United States. Canada and the UK use a mix of metric and imperial units while the US uses customary units, so students, engineers, travellers and shoppers in all three countries switch between them often.

UK Fluid Ounces to Cubic Inches without a calculator
- Closer estimate: multiply by 1.7 (within 2%).
- Fraction trick: multiply by 19, then divide by 11 (within 0.38%).
Real-world imp fl oz to in³ examples
| Example | UK Fluid Ounces | Cubic Inches |
|---|---|---|
| One imperial pint | 20 imp fl oz | 34.6774 in³ |
| Half a pint | 10 imp fl oz | 17.3387 in³ |
| One imperial fluid ounce | 1 imp fl oz | 1.73387 in³ |
| A 350 cubic-inch V8 engine | 201.86 imp fl oz | 350 in³ |
| One US gallon | 133.228 imp fl oz | 231 in³ |
How exact is the imp fl oz to in³ factor?
The factor is exact by definition, so any error comes only from rounding. Round the final answer, not the factor, and match the precision of the number you started with.
Mistakes to avoid
- This page uses the imperial (UK) measure. A US measure with the same name is smaller, so make sure your source is British or older Canadian.
- Volume factors are the cube of length factors, so a small rounding error in the length becomes three times larger in the volume.
