BAR to PSI Conversion

Maintaining proper tyre pressure is paramount for ensuring safety, increasing fuel efficiency, and prolonging tyre lifespan. Find the right tyre pressure for your car tyres using the BAR to PSI conversion table available at Tire Streets. Tyre pressure is commonly measured in BAR (bars), PSI (pounds per square inch) and kPa (kilopascal), and it is no different in the UK.

Let’s understand BAR pressure and how to convert BAR to PSI below:

What is BAR pressure?

BAR pressure is a metric unit used to measure pressure, equivalent to 100,000 Pascals. It represents the force exerted by a fluid per unit area, similar to the force of a 10-meter column of water.

How to convert BAR to PSI:

Converting BAR to PSI is a simple process. 1 Bar is approximately equivalent to 14.504 PSI. So, the BAR to PSI formula is:

Bar x 14.504 = PSI.

For example: 2.5 BAR to PSI is 36.36 PSI. This is calculated using the formula:

2.5 (BAR) x 14.504 = 36.26 PSI.

And, if you have a pressure of 2.2 BAR, the equivalent pressure in PSI would be 31.91 PSI.

When does BAR to PSI conversion help?

You might be living in a country where the imperial measurement system is dominant, and you purchased a car from another country where the metric system is used. It is then essential to know BAR to PSI conversion and vice versa.

It is also helpful when reading vehicle manuals and manufacturer guidelines to find the right tyre pressure in PSI.
