# PSI To Bar Conversion Calculator + 0.01-1000 PSI To Bar Chart

Converting PSI to bars is easy. Both PSI (Pounds per Square Inch) and bars are the most commonly used units of pressure. To make the conversion insanely easy, we created an online PSI to bar calculator (insert PSI, get bars) and a 0.1-1000 PSI to bar conversion chart.

Quick Example: In the photo above, we see that we set the tire pressure to 35 PSI. How many bars is that? Just insert 35 PSI in the calculator, and you will see that this is equal to 2.41 bars right away.

Here is this online calculator you can use whenever you need to make this conversion:

Let’s say you want to convert 48 PSI to bars. You just input ’48’ in the PSI input field, hit ‘Calculate’, and you get this result (screenshot):

We can see right away that 48 PSI is equal to 3.31 bars. If you need this conversion in reverse – bar to PSI – you can check this bar to PSI calculator.

Alright, let’s have a look at the math behind this conversion:

### PSI To Bar Formula

PSI and bars are both units of pressure. However, PSI is defined as a force of 1 pound exerted on an area of 1 square inch, while the bar is defined as a force of 100,000 N (Newtons) exerted on a surface area of 1 square meter. It’s hard to see how to make the conversion between these 2 pressure units from their definitions, but we can just apply this simple rule:

1 PSI = 0.0689475729 Bar

Namely, PSI is a much smaller unit of pressure than bars. 1 PSI is equal to about 0.07 bar. Using this conversion rule, we can write the following PSI to bar formula:

Bar = PSI Ã— 0.0689475729

We see that we have to multiply the pressure expressed in PSI by a factor of 0.0689475729 to get pressure expressed in bars.

Quick Example: How many bars are in 50 PSI? Let’s just put 50 PSI in the equation above and calculate the resulting bars equivalent like this:

Bar (50 PSI) = 50 PSI Ã— 0.0689475729 = 3.45 Bars

We see that 50 PSI is equal to 3.45 bars. Let’s have a look at the full conversion chart where we converted anywhere from 0.1 to 1000 PSI into bars:

Using this chart, you can now just read off the psi-bar equivalent. With the calculator above, you can insert any amount of PSI and you will get how many bars is that amount of PSI.
