Displacement Calculator

Anyone have an engine displacement calculator? I have searched with no luck.

There are a few different ones but I use

Bore x Bore x Stroke x .0007854 x # of cylinders = CC's

I don't really know of any online calculators. I doubt you'll find very many of them, because the equation is so simple.

If it helps, I can explain how the equation is derived.

I just use the standard geometric formula to find the volume of a cylinder.

(Bore/2)^2 * 3.14 * Stroke = CC

note: ^2 means squared ^3 means cubed.

300ex. 74mm x 65.5mm stroke = (74mm/2)^2 * 3.14 * 65.5mm = 281562mm^3 = 282cm^3

I'd be interested in seeing that anyways, though I think I may already understand it.

Just what I was looking for, thanks everyone. :)
