How Engine Displacement Is Calculated
If the engine measurements use different units, convert bore and stroke measurements to consistent length units before calculating displacement; do not mix inches and millimetres within one calculation.
Engine displacement is the combined swept volume of all cylinders in an engine. It is determined by the cylinder bore, piston stroke, and number of cylinders.
One liter equals approximately 61.024 cubic inches. One cubic inch equals approximately 16.387 cubic centimeters.
