Engine Displacement Calculator

Calculate engine displacement from bore, stroke, and cylinder count. Displacement indicates engine size and potential power.

Displacement = π × (Bore/2)² × Stroke × Cylinders

Result is in cubic mm, divide by 1000 for cc. A 2.0L engine = 2000cc. Common conversions: 1L = 61 cubic inches.

What is 'square' vs 'oversquare' vs 'undersquare'?

Square: bore = stroke. Oversquare: bore > stroke (high RPM power). Undersquare: stroke > bore (low-end torque).

Does larger displacement mean more power?

Generally yes, but turbocharging changes this. A 2.0L turbo can match a 3.0L naturally aspirated engine.
