There is no normal reading. It changes from the load put on the motor vs. RPM. i.e. how far open the throttle blade is vs. rpm. At WOT you should be seeing ~105kPa. At idle it's different according to the cam, heads, intake, and tune. My car with just bolt-ons idled at around 28-32kPa depending on ECT and IAT. My car with myh/c and other goodies idles at 52-56kPa. My friends car with almost the same setup as mine but cam on a 114lsa idles between 42-46kPa.
I know in my tuning software I can change the gauge to read in/Hg.
