Displacement: The volume an engine cylinder holds between the top dead center and bottom dead center positions of its piston, measured in cubic inches, cubic centimeters, or (with American cars) liters.
The formula to determine displacement is this:
0.7854 (a derivative of pi) x cylinder diameter squared x length of piston travel x engine's total number of cylinders.
Or, more succintly: 0.7854 x bore squared x stroke x number of cylinders = displacement.
That's directly from my Engines class notes. My teacher is an ASE-certified former GM technician, so he had a lot of useful information.

Yeah, what he said...
Except that it isn't always measured in cc. Sometimes in cubic inches. Displacement is really just the volume of the area that the piston or pistons travel in a single cycle of the engine.

it fairly is technically the swept part of the combustion chamber. In math words, in case you took a cylinder, and made the top equivalent to the engines stroke, and the diameter equivalent to the engines bore. parent that quantity, then multiply it by way of the variety of cylinders, and that's the litres. it fairly is basically how plenty fluid each and all of the pistons interior the engine blended can flow in one million stroke each and each.

An engines displacement is the volume of the cylinders, determined by bore size and stroke.

displacement is the travel of the piston in the chaimber mesured in ccm

It's the bore x pi x stroke, multiplied by the number of cylinders.
