Bore is the diameter measurement of the cylinders in a piston engine.

Engine displacement is calculated by:

{\mbox{displacement}}={\pi  \over 4}\times {\mbox{bore}}^{2}\times {\mbox{stroke}}\times {\mbox{number of cylinders}}

The term "bore" can also be applied to the bore of a locomotive cylinder.
