How Engine Displacement Is Calculated

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.

Displacement = π ÷ 4 × Bore² × Stroke × Cylinders

One liter equals approximately 61.024 cubic inches. One cubic inch equals approximately 16.387 cubic centimeters.
