How to Convert PSI to Bar
To convert PSI to Bar, multiply the PSI value by 0.0689476. For example, 35 PSI x 0.0689476 = 2.4132 Bar.
For the reverse direction, multiply Bar by 14.5038 to get PSI. The swap button above changes the calculator from PSI to Bar into Bar to PSI.
The PSI to Bar Conversion Formula
Bar = PSI x 0.0689476
PSI = Bar x 14.5038
PSI means pounds per square inch. Bar is a metric pressure unit equal to 100,000 Pascals.
Tire Pressure: PSI vs Bar Explained
In the United States, tire pressure is usually shown in PSI. Many passenger cars sit around 30 to 36 PSI, but the correct value is the one printed on the driver's door jamb or in the owner's manual.
In Europe, Asia and many other regions, tire pressure is often shown in Bar. A normal car tire pressure range is roughly 2.0 to 2.5 Bar.
PSI to Bar conversion is useful when using an imported gauge, renting a car abroad, or comparing tire recommendations written in different units.
Common Car Tire Pressure: PSI to Bar
| PSI | Bar |
|---|---|
| 30 PSI | 2.07 Bar |
| 32 PSI | 2.21 Bar |
| 35 PSI | 2.41 Bar |
| 36 PSI | 2.48 Bar |
| 38 PSI | 2.62 Bar |
| 40 PSI | 2.76 Bar |
| 42 PSI | 2.90 Bar |
Who Uses PSI to Bar Conversion?
Car Owners and Drivers
Drivers use PSI to Bar conversion when a tire gauge, dashboard display, or manual uses a different unit. Correct tire pressure helps with safety, braking, fuel economy, and tire wear.
Cyclists and Bicycle Riders
Bicycle tires and pumps often show both PSI and Bar, especially for road and mountain bikes. Accurate conversion helps riders set pressure for grip, comfort, and puncture resistance.
HVAC and AC Technicians
HVAC technicians may see refrigerant pressure specified in PSI or Bar depending on the equipment and region. A fast converter helps avoid mistakes during diagnostics and charging.
Scuba Divers
Scuba tank pressure is commonly shown in PSI in the US and Bar in many other places. Divers use conversion to understand cylinder ratings and compare gauge readings.
Industrial and Engineering Applications
Hydraulic systems, pneumatic tools, pressure vessels, and machinery specifications can use either PSI or Bar. Engineers and technicians convert pressure values when checking specs, limits, and documentation.

Frequently Asked Questions
How do you convert PSI to Bar?
Multiply the PSI value by 0.0689476. For example, 35 PSI x 0.0689476 = 2.413 Bar.
What is 32 PSI in Bar?
32 PSI is equal to 2.206 Bar. This is a common tire pressure for many standard passenger vehicles.
What is the difference between PSI and Bar?
PSI is an imperial pressure unit used mainly in the US and UK. Bar is a metric pressure unit used internationally. 1 Bar = 14.5038 PSI, and 1 PSI = 0.0689476 Bar.
What is normal tire pressure in Bar?
Normal passenger car tire pressure is typically 2.0 to 2.5 Bar, or about 29 to 36 PSI. Always check the recommended pressure on your vehicle door jamb sticker or owner's manual.
Is 2.5 Bar the same as 36 PSI?
Very close. 2.5 Bar equals 36.26 PSI, so 2.5 Bar and 36 PSI are often used interchangeably for tire inflation.
