# Engine displacement calculator

Use our engine displacement calculator to calculate an engine's displacement based on the number of cylinders, bore size and stroke length.

## Input values

## Result

Engine displacement:

**in**^{3}## Understanding the different parameters

### Number of cylinders

This is quite simply the number of cylinders your engine has. What more could we say?

### Bore size

The bore size is the diameter of each cylinder.

### Stroke length

The stroke length is how far the piston travels inside the cylinder.

## How to calculate engine displacement

The formula to calculate an engine's displacement can be seen below, this is what we use in the calculator above.

Engine displacement = π(½ × bore size)^{2} × stroke length × number of cylinders
