Engine displacement formula

    • How do you calculate the displacement of an engine?

      Determine the cubic inches of displacement for that one cylinder by dividing measured diameter by 2 to get its radius, squaring that number, multiplying by 3.14159 (this yields the area of the piston face), then multiplying that result by the measured stroke. Multiply that result by the number of cylinders to find the total engine displacement.


    • What is the equation for engine displacement?

      The equation for calculating displacement is: Engine displacement = π/4 * bore² * stroke * number of cylinders. Displacement is usually measured in liters (L), cubic centimeters (CC), or cubic inches (CI).



    • Does displacement have a calculate formula?

      You will use these units of measurement to calculate displacement, or how far out of position the object is based on its original point. The resultant displacement formula is written as: S = √x²+y². "S" stands for displacement. X is the first direction that the object is traveling and Y is the second direction that the object is traveling.
