How to Convert bar to psi and do it swiftly and without mistakes

Let’s talk about pressure. However, it is not about what one may feel every day at work. Pressure is also a physical quantity widely used by certain specialists or at schools and universities by those who deal with physics.  

In this case, to operate with pressure and solve different tasks that may appear, one has to know the units for it and how to convert them. What to do if you need to convert the bar to psi? Here is the answer.

Bar unit and psi and more

First of all, we’ll need a basic understanding of the subject. Pressure appears when one applies a force to some space. Both these components may have different units. Therefore, the resulting units also vary.

Pascal (Pa) is used as a general one and was named after the scientist who proposed using it in practice. One pascal is equal to one newton per square meter, which is a really tiny value. That is why you may find such values as kilopascals more often utilized in practice, together with a variety of other options.

For instance, bar units are another helpful option but do not belong to the standard category. One bar corresponds to 100,000 Pa. The exact value possesses average pressure on our planet at sea level.

The scientist who proposed to use it in practice, developed techniques for forecasting the weather and bar unit appeared to be more suitable for this purpose. Even nowadays, it is widely utilized in this area.

One more unit—psi—is the pound per square inch. A 1 psi will appear if a corresponding force is applied to this area. If we want to convert it to Pa, 1 psi equals 6895 Pa.

These are just a few examples, but we can see their versatility. 

How do I convert the bar to psi and PSI to Bar?

Given the variety of units, the question of how to work with them swiftly may appear. What should one do, for instance, to convert 1 bar to psi or 3 bar to psi? Working with SI units is easier, but here, the task becomes challenging. To convert bars to pounds per square inch (PSI), you can use the following formula:


Here’s a breakdown of the formula and an example:

  1. Formula Explanation:
    • The conversion factor from bars to PSI is approximately 14.5038. This factor represents the conversion of pressure units from metric (bars) to imperial (PSI).
  2. Example: Let’s say you have a pressure of 3 bars and want to convert it to PSI.
    • PSI=3 bars×14.503
    • PSI=43.5114
    • So, 3 bars equals 43.51 PSI.

Here’s how to use the formula along with an example from PSI to bars:

  1. Formula Explanation:
    • To convert PSI to bars, you must divide the pressure value in PSI by the conversion factor 14.5038. This factor converts pressure units from imperial (PSI) to metric (bars).
  2. Example: Let’s say you have a pressure of 50 PSI and you want to convert it to bars.
  3. bar=50 PSI/14.5038
  4. bar=3.4474, So, 50 PSI is approximately equal to 3.45 bars.

Remember that this formula provides an approximate conversion. For precise calculations, you might need to consider more accurate conversion factors or consult standard conversion tables.

There are some special online converters helpful for this purpose. They work as follows:

  • The user opens the website with a converter;
  • He finds the physical quantity of interest;
  • Then, he has to choose the required units and fill in the initial value.

The result will instantly appear on the screen in the chosen units. Moreover, one can repeat a conversion for another value or change the resulting units. The user can copy and send the results to another device or person.

Online converters such as allow one to work with numerous pressure units. They have all the possibilities you can imagine. In addition, the algorithm works accurately and swiftly and provides correct results instantly. Thus, with the help of such a tool, you can check the manual calculations if needed.

Moreover, this online tool is fully accessible. There is no need to register or create an account on the website. One can visit it whenever he needs swift and accurate calculations and use it as often as required. Conversion of physical quantities was never before so easy and fantastic. Do not hesitate to try!
