The stock gauge on my 04 wrx reads in MPa (megapascal).
1 megapascal = 145.03773801 pound/square inch or reading from the gauge 0.1 megapascal = 14.503773801 pound/square inch.
Keep in mind that the pressure readings are gauge not absolute.
This means that 0 boost still = ~14.7 psi (14.7 pound/square inch = 0.10135293202 megapascal) atmospheric pressure.
