    This is probably a really stupid question but since we all know I am a nooB bear with me

    what is one boost bar equilivalent to in psi I have an APC boost guage and it has like five hash marks before the 1 bar it goes up to 15, down to negative 10 and rests of course at zero but can anyone tell me how to effectively read it

    thanks

    1 bar = about 14.5 PSI.

    SiR Kid is correct
    1 bar = 14.50377 pound/inch^2

    yeah your both right. its not the same as atmospheric pressure.

    i bar is equal to .9869 atmoshere (14.7 psi at sea level)

    14.50743 psi

    I covered both bases with the "about" that I threw in there. :p

    So is it just coincidence that 1 kg/cm^2 is *about* equal to 1 bar? I think 1 kg/cm^2 = 14.2 psi or something??

    1 kg/cm^2 = 1 bar.

    "Bar" is a technical term for pressure like "Newton" is a term for force. It is a short term for a wordy and complicated unit of measure.
