how or what is the math to convert a cc into a decimal... im trying to figure out what a 76cc is in a decimal form so i can replace that # with the 68cc decimal to figure out my compression ratio

76 is a decimal..... 76.00 cubic centimeters.

Here's a couple of sites that may help you.

Not sure what you mean by "decimal", but if you mean convert CCs to cubic inches to add up your total volume to calculate CR, here ya go:

78cc=4.76ci

68cc=4.15ci

I have this website bookmarked, comes in handy:

you can also convert using google shortcuts. for example do a google search for "76cc in ci" without the quotes of course. actually I just tried it and you have to type "76 cubic centimeters in cubic inches" and it will convert for you. most measurements you can just use the abbreviations for though.

Conversion factor for CC to Cubic Inches is 16.38. 78cc divided by 16.38 = 4.76.
