Engine displacement is the total volume of air/fuel mixture an engine can draw in during one complete engine cycle. It is often expressed in cubic centimeters (cc) or liters. To find the volume of a single cylinder, you need to determine the area of the cylinder's base using the bore size and then multiply this area by the stroke length.

Once you have the volume of one cylinder, you then multiply this volume by the number of cylinders in the engine to get the total engine displacement.

By entering the bore size, stroke length, and number of cylinders into the calculator, it will perform these calculations for you, providing the total engine displacement.
