Frequently asked questions
What is the source unit in this conversion?
The source unit is the Bar (bar). A bar is exactly 100,000 pascals.
What is the destination unit in this conversion?
The destination unit is the PSI (psi). Pounds per square inch.
How do I convert Bar to PSI?
Multiply the Bar value by 14.5038. For example, 10 bar × 14.5038 = 145.038 psi.
Is the Bar to PSI conversion exact?
Yes. Both units belong to the same engineering measurement family (pressure and mechanical stress), so the ratio between them is a fixed, defined value rather than a measured approximation.
Where is this conversion commonly used?
It's used whenever a value expressed in Bar needs to be compared with, or reported in, PSI, such as in engineering, scientific, or industrial calculations.
Can I convert PSI back to Bar?
Yes. Multiply the PSI value by 0.0689476 to get Bar.

About this conversion
This page converts Bar (bar) to PSI (psi) within the engineering converter.
A bar is exactly 100,000 pascals. Pounds per square inch.
The formula is psi = bar × 14.5038, based on each unit's fixed relationship to the pressure and mechanical stress base unit.
The conversion is exact, since it relies on a fixed numerical ratio between the two units rather than a measured or approximate value.
