Convert psi to bar

The calculator allows you to convert psi (pounds per inch square) to bar.

Perform the reverse calculation: convert bar to psi

1 psi = 0,0689476 bar (approximately egal to)
1 bar = 14.5038 psi (approximately egal to)

To convert psi to bar, divide by 14.5038.

Example 1

We are going to convert a pressure p of 30 pounds per inch square (psi) to bar.
Pressure p = 30 psi
1 psi = 1 / 14.5038 bar (approximately egal to)
p = 30 psi = 30 / 14.5038 = 2.07 psi (approximately egal to)

Other examples

Here are three more examples of converting psi to bar using a conversion factor of 14.5038:

Convert 50 psi to bar:
50 psi = 50 / 14.5038 = 3.45 bar

Convert 100 psi to bar:
100 psi = 100 / 14.5038 = 6.89 bar

Convert 200 psi to bar:
200 psi = 200 / 14.5038 = 13.79 bar

To read the table, you can follow the rows and columns to find the conversion between psi and bar. The first row of the table contains the headers, which are "Pressure (psi)" and "Pressure (bar)". The subsequent rows contain the conversion values. For example, to find the Bar equivalent of 25 psi, you would look for the row in the table where the psi value is 25. Then, you would follow that row to the "bar" column and read the value listed there, which is 1.72.

Psi (pound per inch square)

Psi stands for "pounds per square inch" which is a unit of pressure. It is defined as the pressure exerted by a force of one pound-force applied to an area of one square inch.

Pressure is a physical quantity that is commonly measured using various units of measurement. Pressure is defined as the force applied per unit area, and is expressed in units such as pascal (Pa), bar, pounds per square inch (psi), and atmosphere (atm), among others.

Bar

Bar (symbol: bar) is a unit of pressure. One bar is defined as the pressure exerted by a force of one newton applied over an area of one square meter. This is equivalent to 100 000 pascal (Pa) or 100 kilopascal (kPa). In other words, 1 bar is equal to 0.1 megapascal (MPa).
