kPa to psi conversion

[MacGuyver]

Hey I have a mechanical boost controller set to 10 psi on my car, and a little while ago I had a FMIC put in. Just recently I've installed a mechanical boost guage (Apexi) which reads boost pressure in kPa. I've been for a few 'spirited' runs and noticed the guage telling me I have a max boost reading of just over 10 kPa. Now according to the formula: psi = Kilopascals x 0.1450, the guage is telling me that I'm now running just over 1.45psi. Does this sound correct, or have I missed something? Or is the guage just really innacurate?

well if i remember back to my year 12 chemistry days, then:

1 atmosphere = 14.3psi = 101.325kPa = 760mmHg

so...

10kPa / 101.325 * 14.3 = 1.41psi

now comes to the next point...

does it feel like its running no boost?

what is the maximum and minimum values on the gauge?

my bet is that in the corner of the gauge it says something like x10 and in fact 10 on the gauge is 100kPa...

good luck!

No it doesn't feel like it's running no boost, but I have noticed a drop in boost on the stock boost guage. The maximum value on the gauge is 200kPa (each increment is x100 kPa). Just really wondering if installing an intercooler would result in such a large drop in boost.
