How to convert an engine's compression ratio to PSI (pounds per square inch):

(X*14.696)/1

(14.696 is standard atmospheric pressure at sea level.)


Examples:

Suzuki FA50 compression ratio is 6.5:1

(6.5*14.696/1 = 95.524 PSI)

Sachs A engine compression ratio is 8:1

(8*14.696/1 = 117.568 PSI)

Sachs D engine compression ratio is 10:1

(10*14.696/1 = 146.96 PSI)
