Ok, trying to figure out compression ratio on a proposed build, maybe need an education on the subject. Have a couple assumptions I need help with.

Inch to cm conversion is inch x 2.54?

Volume of a cylinder is: stroke x 3.14159 x 1/2 bore squared, right? Of course must add in head gasket cc, head cc, and subtract any dome?

"Top dead center cc" is head cc + head gasket cc + cc of any amount the piston is short of the deck?

compression ratio is how many times the top dead center volume fits into the total cylinder volume? (Total cylinder volume/top dead center volume?)

so, tell me if Using stuff from geometry works for this or not, thanks guys!
