Bore and Stroke Calculator
Calculate engine displacement from bore and stroke measurements. Determine your engine’s size in liters, cubic inches, and cubic centimeters.
Step 1: Engine Dimensions
Understanding Bore and Stroke
Bore is the diameter of each cylinder, while stroke is the distance the piston travels within the cylinder. Engine displacement is calculated from these measurements and the number of cylinders.
Step 2: Additional Options
About Engine Displacement
Engine displacement is the total volume of all the cylinders in an engine. It’s a key factor in determining an engine’s power potential, fuel consumption, and emissions. Larger displacement engines typically produce more power but consume more fuel.

Displacement Calculation 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 and stroke measurements are typically in millimeters, and the result is converted to liters, cubic inches, or cubic centimeters.
Example: 86mm bore, 86mm stroke, 4 cylinders = (3.1416/4) × 86² × 86 × 4 = 1,998,000 mm³ = 1,998 cc = 2.0 L
