How it is calculated

  • Cubic inches to litres: multiply by 0.016387064
  • Litres to cubic inches: divide by 0.016387064 (about 61.0237)
  • It follows from 1 inch = 2.54 cm, cubed, then 1,000 cm³ = 1 litre

To work from the engine’s bore and stroke, use the engine displacement calculator.

Worked example

  • 100 in³ × 0.016387064 = 1.6387 L
  • 2 L ÷ 0.016387064 = 122.0475 in³

Why your number may differ

Engine sizes are rounded by makers, so a nominal 350 in³ can be a little different in practice.
