Superheat formula.

Subtract the two numbers to get superheat. For example, 68 psi suction pressure on a R-22 system converts to 40 ° F. Let's say the suction line temperature is 50 ° F. Subtracting the two numbers gives us 10 ° F of superheat. Superheat for most systems should be approximately 10F measured at the evaporator; 20 ° F to 25 ° F near the compressor.
