What is the Formula for converting cubic inche?

Answer 1

You don't say what you want to convert cubic inches to, but I'm guessing that you want to convert it to cc's or liters; so I will give both formulas. There are 2.54 cm per inch; so you need to cube that number to convert to cc's. Cubing 2.54 gives 16.39 cc's per cubic inch. To get liters, just divide cc's by 1000. Example: Give the size of a 350 cubic inch engine in cc's and liters. 350x16.39=5736 cc's, or 5.7 liters.
