Enter the piston radius (cm), the piston length (cm), and the number of pistons (cm) into the Engine Volume Calculator. The calculator will evaluate and display the Engine Volume. 

Engine Volume Formula

The following formula is used to calculate the Engine Volume. 

Ve = pi*r^2*L*n
  • Where Ve is the Engine Volume (cm^3)
  • r is the piston radius (cm) 
  • L is the piston length (cm) 
  • n is the number of pistons (cm) 

To calculate the engine volume, multiply the piston radius squared by 2 times the piston length times the number of pistons.

How to Calculate Engine Volume?

The following example problems outline how to calculate Engine Volume.

Example Problem #1

  1. First, determine the piston radius (cm).
    1. The piston radius (cm) is given as 2.5.
  2. Next, determine the piston length (cm).
    1. The piston length (cm) is calculated as: 4.
  3. Next, determine the number of pistons (cm).
    1. The number of pistons (cm) is found to be: 6.
  4. Finally, calculate the Engine Volume using the formula above: 

Ve = pi*r^2*L*n

Inserting the values from above yields: 

Ve = pi*2.5^2*4*6 = 471.238 (cm^3)

Example Problem #2

The variables needed for this problem are provided below:

piston radius (cm) = 3

piston length (cm) = 5

number of pistons (cm) = 4

This example problem is a test of your knowledge on the subject. Use the calculator above to check your answer. 

Ve = pi*r^2*L*n = (cm^3)
