About Bar and PSI Pressure Units
What these units mean and where each one is used
bar Bar
The bar is a metric unit defined as exactly 100,000 pascals, close to standard atmospheric pressure (1.01325 bar). It is the everyday pressure unit across Europe and most of the world - tire pressure stickers, compressor gauges and industrial specs commonly read in bar.
psi PSI
PSI (pounds per square inch) is the standard pressure unit in the United States and a few other countries. American tire sidewalls, shop compressors and industrial equipment label pressure in PSI. 1 bar = 14.503773773 PSI.
x14.5 The Conversion Formula
To convert bar to PSI, multiply by 14.503773773. To convert PSI to bar, divide by 14.503773773 (or multiply by 0.0689475729). For everyday tire work, the approximation 1 bar ≈ 14.5 PSI is accurate to about 0.03%.
2.2 Tire Pressure Quick Tips
Passenger-car tire pressure typically falls between 2.0 and 2.5 bar (29-36 PSI). Always check the sticker on the driver-side door jamb or the owner manual, and measure cold - driving even a few kilometers heats tires and raises the reading by roughly 0.1-0.3 bar.
Frequently Asked Questions
How many PSI is 1 bar?
1 bar equals 14.503773773 PSI, commonly rounded to 14.5 PSI. So 2 bar is about 29 PSI, and 2.5 bar is about 36.3 PSI.
How do I convert bar to PSI?
Multiply the bar value by 14.503773773. For example, 2.2 bar × 14.503773773 = 31.91 PSI. To go the other way, divide the PSI value by 14.503773773 - or just type your value into the converter above and read off every unit at once.
What is 2.2 bar in PSI for car tires?
2.2 bar is 31.91 PSI, a typical recommended pressure for compact and mid-size passenger cars. Other common tire values: 2.0 bar = 29.01 PSI, 2.3 bar = 33.36 PSI, 2.4 bar = 34.81 PSI, and 2.5 bar = 36.26 PSI.
Are bar and psi interchangeable on gauges?
They measure the same thing - pressure - but use different scales, so always convert rather than guess. Many modern tire gauges and compressors show both scales on the same dial or display, marked bar on one side and psi on the other.
