Our cubic inch calculator will work out the total cubic inches of displacement (cid) for an engine given its bore, stroke and number of cylinders. The cubic inches of an engine is the measure of the swept volume of all of the pistons in the bores, not including the combustion chamber itself.

The formula for this cubic inch calculator is

cid = (((Bore/2)^2) x Stroke x Pi) x Cyl
