The control panel of the software show's almost all the conversion you need. The dial to the left of the tach & above battery voltage show's vacuum in PSI. The small box below the voltage dial, third from the left, is vacuum in KPA. To convert PSI to inches of vacuum, multiply by 2. (-15 psi is 30" of vacuum, -2 psi is 4" of vacuum)
