Engine Size Calculator — Calculate Your Vehicle’s Engine Displacement

Engine Size Calculator

Calculate your vehicle’s engine displacement in liters, cubic inches, and cc. Understand how bore, stroke, and cylinder count affect engine size.

Step 1: Engine Specifications

Understanding Engine Displacement

Engine displacement is the total volume of all the cylinders in an engine. It’s calculated using the bore (cylinder diameter), stroke (distance the piston travels), and number of cylinders.

Step 2: Additional Options

About Engine Displacement

Engine displacement is a key indicator of an engine’s potential power output. Generally, larger displacement engines produce more power, but modern technology allows smaller engines to achieve impressive performance through turbocharging and advanced engineering.

Engine Displacement Formula

Displacement = π/4 × Bore² × Stroke × Number of Cylinders

Engine displacement is calculated using the formula for cylinder volume multiplied by the number of cylinders. The bore is the diameter of each cylinder, and the stroke is the distance the piston travels within the cylinder.
