BAR / PSI chart

HOW DO YOU CONVERT PSI TO BAR?

To convert psi to bar (the metric unit of pressure), use this formula:

iiiiiipsi x 0.07 = bar

iiiiiiExample: 30 psi x 0.07 = 2.1 bar

To convert bar to psi, use this formula:

iiiiiibar x 14.5 = psi

iiiiiiExample: 2 bar x 14.5

er, dude, 1 bar = 14.7psi,

its as easy as diving psi by 14.7 for bar

or multiplying bar by 14.7 for psi.

even if 1 bar was 14.5psi, using 0.07 as a multiple to convert psi to bar is inaccurate, as 30 psi divided by 14.5 = 2.07, not 2.1. The higher the boost the less accurate the calculation.

mmmm just goes to show not everything you find on the net is correct , thanks Steve

Ah but what about mmHG..?? haha I think its about 1 bar is 18mmHG but i cant remember and cat be buggered looking up.

DAMN Standard boost gauge.!

Ok, I know I'll be hearing the typical "There's one in every crowd!" but here goes:

1 Bar = 14.50377 psi = 0.9869233 atmosphere = 75.00617 cm of mercury = 29.52999 inches of mercury = 1.019716 kg/cm2 = 100 kpa = 1000000 dyne/cm2 = 1.044272 tons/foot2 = 750.0617 torr.

...and the list goes on. Have fun quoting that your car runs "x" tons per square foot boost pressure.
