Formula
The Engine Displacement Calculator uses the formula:
Displacement (cc) = 3.141592653589793 ÷ 4 × Bore ^ 2 × Stroke × Number of cylinders ÷ 1000
Worked example
For example, with bore of 84 mm, stroke of 90 mm and number of cylinders of 4, the displacement (cc) is 1,995.
| Bore | 84 mm |
|---|---|
| Stroke | 90 mm |
| Number of cylinders | 4 |
| Displacement (cc) | 1,995 |
|---|---|
| Displacement (litres) | 2.00 |

Frequently asked questions
Displacement is π ÷ 4 × bore² × stroke × cylinders. An 84 mm bore, 90 mm stroke, 4-cylinder engine is about 1995 cc, or 2.0 litres.
Bore is the cylinder's diameter and stroke is how far the piston travels. Together they set the volume each cylinder displaces.
Engines are often quoted in litres for marketing. Divide cc by 1000 — so 1995 cc is about a 2.0-litre engine.
Generally larger engines can make more power, but turbocharging, tuning and efficiency mean a smaller engine can match a bigger one.
