PSI to BAR Conversion

At Tire Streets, we understand the significance of tyre pressure and its impact on your vehicle's performance and safety. Tyre pressure is commonly measured in PSI (pounds per square inch), BAR (bars), and kPa (kilopascal), and it is no different in the UK.

If you’re wondering how to convert BAR to PSI, you can check out our ‘BAR to PSI Conversion’ calculations here.

Now, let’s understand PSI and how to convert PSI to BAR below:

What is PSI?

PSI stands for "pounds per square inch” and is a unit of pressure often used in the United States and other countries following the imperial measurement system. It measures the amount of force exerted on a surface area of one square inch.

What is PSI in Tyre Pressure?

In the context of tyre pressure, PSI is a unit of measurement used to quantify the pressure exerted by air inside a tyre. It indicates the force applied by the air within the tyre onto a square inch of the tyre's inner surface area.

Your car tyres need to have proper tyre pressure for maintaining traction, stability, fuel efficiency, and overall safety on the road.

How to convert PSI to BAR?

Converting PSI to BAR is a straightforward process that involves a simple formula. Here's the PSI to BAR conversion formula:

1 PSI = 0.0689476 BAR

To convert PSI to BAR, simply multiply the pressure value in PSI by 0.0689476. For example:

30 PSI * 0.0689476 = 2.068428 BAR

 

You can also convert PSI to BAR using an alternative method where one BAR is equivalent to approximately 14.504 PSI. Thus, to convert PSI to BAR, divide the PSI value by 14.504.

For example:

To convert 33 PSI to BAR using this method, you will use the below formula:

33 PSI ÷ 14.504 = 2.275234 BAR

FREQUENTLY ASKED QUESTIONS ABOUT PSI TO BAR CONVERSION:

• What is the PSI of 1 BAR?

1 PSI = 0.0689476 BAR

• What is normal PSI?

The "normal" PSI (pounds per square inch) for tyre pressure can vary depending on several factors, including the vehicle make and model, tyre size, and manufacturer recommendations.

Typically, you can find the recommended PSI for your vehicle on a sticker located on the driver's side door jamb, inside the glove compartment, or in the owner's manual.

However, as a general guideline below are the normal PSIs:

Passenger Cars: The recommended PSI for standard passenger cars usually falls within the range of 30 to 35 PSI. This range provides a balance between comfort, handling, and fuel efficiency.

Trucks and SUVs: Trucks and SUVs may require slightly higher tyre pressure due to their heavier weight and load-bearing capacity. The recommended PSI for these vehicles often ranges from 35 to 40 PSI.

High-Performance Vehicles: High-performance vehicles may have specific tyre pressure recommendations to optimise performance and handling. It's essential to consult the manufacturer's guidelines for these vehicles.

 

Pro Tip: It's crucial to check and adjust tyre pressure regularly, preferably when the tyres are cold, as driving can increase tyre temperature and pressure.
