There are many compression ratio calculation tools around the internet and in textbooks, but we've not seen one with all the features of ours:

  • Works in inches or mm.
  • Calculates cubic capacity of the engine.
  • Cylinder head gasket volume can be input directly, or calculated for you.
  • 'Dead area' around the top of the piston can be considered if required.
  • Printing facility for your engine records.
