	The pressure as measured by a guage is 14.7 psi above the zero level which is called "absolute". That is why specifications are in psig (Guage) or PSIA (Absolute). 14.7 is the air pressure at sea level. As you rise in altitude the pressure decreases. Also atmospheric conditions (Storms) can cause changes in air pressure so 14.7 is really only an average. __________________ Kindness knows no boundaries.

	Very clear and to the point The pressure gauge is called a gauge since it is used to measure. Wiki : Gauge (engineering), any of a variety of measuring instrument Webster: 2: an instrument for or a means of measuring or testing: as a: an instrument for measuring a dimension or for testing mechanical accuracy b: an instrument with a graduated scale or dialect for measuring or indicating quantity. by the way what you want it to be called ? __________________ Fantastic ideas for a Fantastic World, I make the illogical logical.They put me in cars,they put me in yer tv.They put me in stereos and those little radios you stick in your ears.They even put me in watches, they have teeny gremlins for your watches

	You see, although not spelt out , I am within the gauges too, who you think is making your gauges (and switches and other thingies _malfunction ? ) and I don't like to be called _{(any other)} names . And should I quote shakespeare ? I have to almost quote that alternate day to my son - why battery + side is called + and other - ? Why pink is called pink ? why not zinc ?

	The exact origination of the word guage is not known, but here are a few suggestions. 1440, from Anglo-Fr. gauge (1357), from O.N.Fr. gauger, from gauge "gauging rod," perhaps from Frank. *galgo "rod, pole for measuring" (cf. O.N. gelgja "pole, perch," O.H.G. galgo, Eng. gallows). __________________ The last fight was my fault. My wife asked "What's on the TV?" I said "Dust!"
