Currently, I'm working on an app which should show Gauge value (inHg) of the vehicle using OBD reader. Which values should I use to show the Gauge? Is there any formula?

"Gauge value" isn't specific enough since it could refer to multiple fluids. Are you talking about intake air, fuel or engine oil?– ZaidAug 28, 2018 at 8:56

@Zaid it should be air and fuel mixture– Chathura WijesingheAug 29, 2018 at 7:00

Gauge pressure (GP) is linked to absolute pressure (AP) by atmospheric pressure as in :
AP = GP + atmos p
Units can be Bar, Pascals, psi, mmH2O, inHg etc
But you can have them selected based on location ie Bar works well in Europe, psi in UK etc
