Calculate the total displacement of an engine from its bore, stroke, and number of cylinders. Displacement is the combined volume all the pistons sweep in one full cycle, and it is one of the biggest factors in how much power and torque an engine can make. The volume of one cylinder is pi divided by four, times bore squared, times stroke, and multiplying by the cylinder count gives the total. This calculator takes bore and stroke in millimeters and returns the displacement in cubic centimeters, liters, and cubic inches, the three units you will see on spec sheets around the world. It is handy for engine builders checking a bored out block, students learning engine math, or anyone converting between a metric and an American displacement figure. All calculations run locally in your browser.
It finds the swept volume of one cylinder from bore and stroke, then multiplies by the number of cylinders.
Bore is the cylinder diameter and stroke is how far the piston travels, together defining each cylinder's volume.
It reports displacement in cubic centimeters, liters, and cubic inches at the same time.
