barrometric pressure is 14.7 psi, so, if you boost 1 bar, you are boosting 14.7.. and you do the math for the rest.

Bar / PSI
------------
.25 / 3.63
.40 / 5.80
.50 / 7.25
.60 / 8.70
.70 / 10.15
.80 / 11.60
.90 / 13.05
1.00 / 14.50

There you go.

Yah, I should have checked my graphing calculator rather than the first page I found on google. 1 bar = 14.503773773 psi

1 bar of boost is 14.7 psi, rounded off 15 psi with that said this is the reason people with turbocharged hondas need to have 3bar map sensors to exceed 30psi. get it 2 15+15=30, 30+=3bar.

not true... a 3 bar reads 1 bar of vacuum and only 2 of positive manifold pressure, so you could almost get 40 psi, almost but not quite

BAR = 14.5 PSI @ Seal Level

In google, type:

"xx psi in bar" where xx is the amount of boost you are running. It will tell you the conversion to BAR @ sea level.

The amount of Boost that BAR is equal to is going to be less for you.

I'll try to find the formula for that, in the mean time- here's a good read on this topic.

For every 1,000 feet in elevation, 1 BAR = approx .5 psi less.

So 1 BAR for you is just a smidge under 14 PSI. . . prob 13.9xx PSI

nope, one atmosphere is 14.7. One bar is 14.5psi.

Are you that lazy, seriously?

1 bar to kg/cm^2

Into google. First result shows that you multiply pressure in bar by 1.02 to get pressure in kg/cm^2. How have you survived 28 years of life if you can't figure that out?

Yeah I did that guys, im not that lazy, but just making sure I had the conversion right because of multiple kilogram options even though common sense tells me cm squared

Whether in BAR or atm, you have to remember that it's all really a measure of pressure for which the SI unit is Pascals (Pa). Pa = 1 N/m^2.

1 atmosphere (atm) is 101,325 Pa but to simplify the mathematical conversions, they came up with BAR which is equivalent to an even 100,000 Pa.
