Assuming you meant to say fluid ounces: 40.58 fluid ounces.
If you mean capacity in the sense of volume, the main unit would of course be the cubic meter; other units used include cubic decimeters (equal to liters), cubic centimeters, cubic millimeters.
Yes, as one inch is 2.54 centimeters, a cubic inch is greater than a cubic centimeter. A cubic inch would be (2.54)^3 (2.54 to the power of 3) cubic centimeters, which is about 16.39 cubic centimeters or cm^3.
16 ounces would equal 1 pint, so 24 ounces would equal 1.5 pints.
If they were the same, there would be no need for different names.1 cubic meter = 1,000,000 cubic centimeters.
Cube it so for example if it was 2 you would do 2x2x2=8 which is 2cm cubed
