Use an instrument such as a force gauge, spring scale or strain gauge. To calculate psi, divide the force applied (F) with the area (A). The psi, or pounds per square inch, is a unit of pressure (P) using the foot-pound-second (FPS) system. Specifically, psi measures pressure or stress, whereas bar only measures pressure. Its official symbol is 'bar' the earlier 'b' is now deprecated, but still often seen especially as 'mb' rather than the proper 'mbar' for. but this is not always the case in heavier cars, such as Large SUVs, the pressure for thier tires can be as. When I'm away from home, or just feel very lazy I use them to pump my tires. They have those large compressors for car tires, but they can easily go over 50psi. good range of pressure in car tires is withing 193-234 in kPa (kilopascal) or 28 to 34 psi (pounds per square inch). I have a cheap (6 from Lidl) foot pump and pump my tires to 5 bar front and 6 bar rear without any problems. The word bar is of Greek origin, báros meaning weight. As we talked about above kPa is often used for car tire pressure, So in the US you need to convert that to psi as this is the common north american value for pressure. The dot indicates the maximum operating temperature when using a 24 V supply and a 250 Ohm resistor. Current Output Operating and Temperature Compensation Note: The operating area is extended with a 250 Ohm resistor. For example, to find out how many bar is 30 psi, divide 30 by 14.5037738, that makes 2.06843 bars equal to 30 psi.Īlso, is PSI same as bar? The key difference between psi and bar is that psi measures pressure as a one-pound force applied on an area of one square inch whereas bar measures pressure as a force applied perpendicularly on a unit area of a surface. The bar is a measurement unit of pressure, equal to 1,000,000 dynes per square centimetre (baryes), or 100,000 newtons per square metre (pascals). MLH Series, 6 bar to 550 bar 50 psi to 8000 psi Issue D 50010132 Figure 2. Bar : The bar is a unit of measurement for pressure. For example, to find out how many psi is 6 bars, multiply 6 by 14.5037738, that makes 87.0226 psi equal to 6 bars.Ĭonsequently, how do you calculate psi to bar?Īs 1 bar is equal to 14.5037738 psi, to convert psi to bar, divide the psi value by 14.5037738. Psi : Psi is the abbreviation of pound per square inch, and is widely used in British and American. To convert bar to psi, multiply the bar value by 14.5037738. How to convert bar to psi? 1 Bar is equal to 14.5037738 Psi.
