Many people need to find out what is the conversion factor from psi to bar when working with tire pressure, compressors, hydraulic systems, or industrial equipment. If you’ve been wondering what the exact PSI to bar conversion factor is, you’ve come to the right place.

In this guide, you’ll learn the official conversion factor, see how the formula works, and find several quick conversion examples from 0.01 PSI to 0.10 PSI.

Let’s begin.

What is the Conversion Factor from PSI to Bar?

The exact conversion factor from PSI to bar is 0.0689476.

This means that every 1 PSI is equal to 0.0689476 bar. No matter whether you’re converting a very small pressure or a very large one, this conversion factor always remains the same.

Whenever you want to convert PSI into bar, simply multiply the PSI value by 0.0689476.

Exact Conversion Factor PSI to Bar

The conversion formula is shown below.

Bar = PSI × 0.0689476

Let’s see it in action.

Suppose you have a pressure reading of 10 PSI.

Insert the value into the formula.

Bar = 10 × 0.0689476

After calculation,

Bar = 0.689476

Therefore, 10 PSI equals 0.689476 bar.

As you can see, the calculation is straightforward once you know the conversion factor.

1 PSI to Bar Conversion Factor

Many users ask specifically about converting 1 PSI to bar.

Fortunately, there’s nothing different to remember. The same conversion factor applies here as well.

Since

Bar = PSI × 0.0689476

then

Bar = 1 × 0.0689476

which gives

Bar = 0.0689476

So, 1 PSI equals exactly 0.0689476 bar.
