Engine Displacement Calculator

Your details

Standard mode calculates displacement. Reverse mode solves for bore when you already have a displacement target.
Total number of cylinders in the engine (e.g. 4 for a typical inline-4 car engine).
The internal diameter of one cylinder (bore). Metric default is 86 mm.

The distance the piston travels from bottom dead centre to top dead centre. Metric default is 86 mm.

1998 cc - 2.00 L - 122 cu in

  • Total displacement is 1998 cc (2.00 L / 121.9 cu in) across 4 cylinders.
  • Bore-to-stroke ratio is 1.000 (square engine). A bore-equal-stroke design balances power and torque characteristics across the RPM range.
  • Each cylinder sweeps 499.6 cc of volume per revolution.

Next stepTo estimate power output, pair this displacement with a compression ratio calculator. For fuel economy estimates, use displacement alongside your fuel economy or fuel cost calculator.
