About Imperial Fluid Ounce and Cubic Centimeter
The imperial fluid ounce is about 28.413 milliliters, slightly smaller than the US fluid ounce, with 20 to the imperial pint rather than 16. Older UK packaging and recipes use it. The cubic centimeter equals exactly one milliliter. Engine sizes (cc), medical syringes, and solid part volumes use it. One Imperial Fluid Ounce equals 28.4130625 Cubic Centimeters (1 imp-fl-oz = 28.4130625 cm3). Imperial Fluid Ounce is used in older UK packaging and in traditional British recipes. Cubic Centimeter is used in motorcycle and small engine sizes (cc).
Precision and Rounding:US and imperial volume units share names but differ in size (an imperial gallon is about 20% larger than a US gallon), so confirm which system a figure uses before converting. Kitchen work tolerates rounding to the nearest milliliter or quarter-teaspoon; fuel, chemistry, and brewing need three or more decimal places.
Conversion factors per NIST Special Publication 811 and the BIPM SI Brochure (9th edition) (reference).
