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)
