About this calculator
What is the Engine Displacement Calculator?
Engine Displacement Calculator calculate engine displacement from bore, stroke, and cylinders. It is part of Home of Calculators's Automotive Calculators suite for fuel cost, car loans, depreciation, and vehicle maintenance. The calculator is designed for drivers, car buyers, mechanics, but anyone can use it. No signup, no ads, no tracking. Just accurate math, computed locally in your browser using a BigNumber-precision math engine.
Formula Reference
The Formula
V = (π/4) × B² × S × C
Engine displacement is the total volume swept by all pistons in an engine. It is calculated from the bore (cylinder diameter), stroke (piston travel distance), and number of cylinders.
Variables
BBore diameter (mm)SStroke length (mm)CNumber of cylindersWorked Example
B = 86S = 86C = 4
Result: ~1998 cc (2.0L)
How to use the Engine Displacement Calculator
- 1
Record bore and stroke
Find the bore diameter and stroke length in millimeters.
- 2
Calculate single cylinder volume
V₁ = (π/4) × B² × S. This gives volume in mm³.
- 3
Multiply by cylinders
Total V = V₁ × C. Convert mm³ to cc by dividing by 1000.
