About Cubic Centimeter and US Fluid Ounce

The cubic centimeter equals exactly one milliliter. Engine sizes (cc), medical syringes, and solid part volumes use it. The US fluid ounce is about 29.574 milliliters, one eighth of a US cup. Beverage cans, cosmetics, and baby formula in the US are labeled in fluid ounces. One Cubic Centimeter equals 0.0338140227 US Fluid Ounces (1 cm3 = 0.0338140227 fl-oz). Cubic Centimeter is used in motorcycle and small engine sizes (cc) and in syringe volumes. US Fluid Ounce is used in US beverage can and bottle sizes.

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).
