How to use the Engine Displacement Calculator

Calculate four-stroke engine swept displacement in cubic inches, cubic centimeters and liters.

Calculation formula

Engine displacement (in³) = π/4 × bore² × stroke × number of cylinders; liters = cubic inches × 0.016387064.

Recommended steps

1. Enter values using the units shown beside each field.
2. Review whether the example assumptions match your situation.
3. Run the calculator and compare the key metrics.
4. Use the source data or official rates when precision matters.

Known limitations
