Engine Size Converter
Convert engine displacement between cc, litres and cubic inches (CID) instantly.
American engines are quoted in cubic inches (a 350, a 454), the rest of the world uses litres or cc, and spec sheets mix all three. This converter translates any engine size into all units at once.
Conversion Formulas
Marketing rounds aggressively: the "5.7 L" small-block is really 349.85 CID ≈ 5.74 L, and the famous "5.0" Mustang is 302 CID = 4.94 L. When precision matters (ordering pistons, registration classes), compute from actual bore and stroke with the displacement calculator.
