Bar to Pounds Chart

I did a couple of searches with no luck. Has anyone published a complete list of Bar versus Pounds for boost. I am so used to reading boost in pounds it is hard to get used to this point this and point that. I know there are conversion tables just wondering if all the work has already been done.

Divide the "psi" By 14.504 to get the "bar", or in turn multiply the "bar" reading by 14.504 to get the "psi".

1BAR=14.695949psi at sea level.
I think 14.7psi would be a better number to use,
the number given 14.504 would be close to 370 feet.
Some other numbers based on your towns average elevation.....
Sarasota and Ft. Lauderdale 20feet+- 14.685psi
Chicago 530feet+- 14.387psi
Not that it matters because we are only talking .2tenths of a psi at 1.2BAR difference between the formula but its late, and im bored and have a calculator nearby lol

After doing the math and seeing the .7-1. numbers I am surprised that with todays technology as far as engine mgmt. intercooler and turbo design that Porsche would produce a car that comes from the factory making less boost stock than my 1986 Buick Grand National that has one small intercooler and engine mgmt. from the dark ages. With only a few mods no internal engine components we regularly run 1.4 and above with absolutely no problems.

Also there is a small program called convert.exe which converts a whole load of different engineering / scientific variables - do a net search you'll find it. T2

I know I'm a bit late to the party on this one, but for what it's worth, Google can do a lot of these. For example:

"0.7 bar in psi"
http://www.google.com/search?source=...le+Search&aq=f

"14psi in bar"
http://www.google.com/search?hl=en&q...ar&btnG=Search

It can also do other fun conversions:
"13454 AU in light years"
http://www.google.com/search?hl=en&q...rs&btnG=Search

Should have stuck with a grand national I suppose...
