Engine displacement is one of the most important specifications when comparing vehicles, engines, or performance upgrades. Depending on where you live or the type of engine you’re dealing with, displacement may be listed in liters (L) or cubic inches (CID or CI).
Modern vehicles typically use liters, while classic American engines, marine engines, and small-block V8s are often measured in cubic inches.
This guide explains the difference between the two units and provides a complete engine liters to cubic inches chart for quick reference.

What Is Engine Displacement?
Engine displacement refers to the total volume of all cylinders in an engine. It indicates how much air-fuel mixture an engine can draw in during one complete cycle.
- Liters (L) are the standard metric measurement used worldwide.
- Cubic inches (CI or CID) are traditionally used in the United States, especially for older and performance engines.
A larger displacement generally means:
- More power potential
- Higher torque output
- Increased fuel consumption
