How many cubic inches equals an ounce?

Answer 1

That depends upon whether you meant fluid ounces -- which measure volume -- or weight ounces. It is possible to convert cubic inches and fluid ounces, since both are units of volume. But weight ounces -- as in 16 ounces to the pound -- is a different story. One ounce of tungsten will occupy far less volume than an ounce of, say, styrofoam! Assuming you mean fluid (or liquid) ounces: 1 ounce [US, liquid] = 1.805 cubic inches.
