1 bar is equal to 100,000 Pascals, which is close approximately to atmospheric pressure, so it is often used to represent atmospheric. It is widely used in the daily life particularly in European countries, though that is a non-SI unit. Bar : The bar is a unit of measurement for pressure. Technically I should have subtraced 1.01 which is 14.7 psi or 29.92 in/hg, but 1 is a lot easier to remember and the results are close enough anyways. 580.15095 Psi (Psi) Visit 40 Psi to Bar Conversion. Which is 14.7 psi or 29.92 in/hg below atmospheric pressure (atmospheric pressure being 0 psi). You guys get the idea.MAP sensor reference starts at absolute vacuum. psi to bar conversion formula: bar psi 0.0689475729 bar psi / 14. Using the simple formulas below, you can easily convert psi to bar. So say we are trying to figure out how much boost a 3 BAR map sensor is good for. Simply multiply 50 by 0.0689475729: bar 50 0.0689475729 3.447378645 bar Therefore, 50 psi equal to 3.447378645 bar. The way I do it is take the manufacturers MAP rating, subtract one, then multiply by 14.5. 1 bar is equal to 100,000 Pascals, which is close approximately to atmospheric pressure, so it is often used to represent atmospheric pressure rather than standard. For example, to convert PSI to kPa, divide the PSI number by 6.895. To do so, switch the formulas around and divide rather than multiply. If anybody else is as confused as me, what Dee is trying to explain is how to find out how much boost a MAP sensor is good for. 333.5868 Psi (Psi) Bar : The bar is a unit of measurement for pressure. Remember, you can also convert from PSI to kPA, and PSI to Bar.
