PSI vs Bar
17 Jul 2019
PSI and bar are the most common units of measurement that are related to pressure. You may need to convert PSI to bar regularly if your pump only measures pressure in one and not the other.
Understanding how these units of measurement work is crucial for maintaining tyre pressure, and it’s necessary to maintain excellent fuel economy. To find out what the recommended tyre pressure for your car is, search for your model today.
Why is it necessary to maintain the recommended tyre pressure?
It is important to maintain the recommended tyre pressure for a few reasons, but safety is the most important one. Well pressurised tyres are safer overall. Tyres that have been inflated to the correct pressure are typically easier to handle, meaning your vehicles steering, stopping and grip will improve. They will also last longer, meaning that your tyres will need replacing less frequently.
Another important reason for maintaining the recommended tyre pressure is fuel economy. Tyres maintained at the recommended tyre pressure will maintain correct friction with the road – using less energy overall.
On the other hand, underinflated tyres can result in a slow response time, increase the risk of aquaplaning, can result in unevenly worn tyres, and can even cause blow outs. Therefore, they are incredibly dangerous, putting drivers, passengers, and the general public at risk.
What is PSI?
PSI is a unit of measurement that refers to the pound-force per square inch. It measures pressure resulting from a force that is applied to an area of one square inch. It can measure everything from blood pressure to tyre pressure.
What is Bar?
Bar is a metric unit of pressure that has been legally recognised by the EU since 2004 for meteorological purposes. The bar and millibar were introduced by the Norwegian meteorologist Vilhelm Bjerknes who founded the modern practice of weather forecasting.
Atmospheric pressure is usually measured in bars and millibars, so some people may be more accustomed to hearing the term used when referring to hurricanes and cyclones. Some engineers also use the bar as a unit of pressure.
