How this calculator works
One cc equals one mL. A US liquid gallon is exactly 231 cubic inches, with 128 US fluid ounces per gallon. That gives exactly 29.5735295625 cc per US fluid ounce. An imperial fluid ounce is 1/160 of a 4.54609 L imperial gallon, or exactly 28.4130625 cc, and appears in the comparison table.
Formula
US fl oz = cc / 29.5735295625; cc = US fl oz x 29.5735295625; imperial fl oz = cc / 28.4130625.
Worked example
100 cc is approximately 3.3814022702 US fl oz or 3.5195079728 imperial fl oz. Two US fl oz is exactly 59.147059125 cc.
