Default RE: Formula for finding out engine size

I'm looking for a formula I saw years ago in an R/C Modeler Magazine that you use to determine the actual engine size. It used piston diameter and stroke. Anyone know what I'm talking about?? Can't find it and need it! Any help appreciated!!!
Something like bore x stroke = displacement
(if measuring in .cm then you'd get CCs, if measuring in .in then you'd get .CI)
