This calculator is intended for use as a general estimate of your compression only. Certain variables that cannot be accounted for may cause the actual compression ratio to vary - such as a head that has been milled. Please use your own descretion.

Default values have been provided for your convenience. You can enter your own custom values in the edit boxes below to match your personal setup as needed.
