Frequently asked questions
What is the source unit in this conversion?
The source unit is the PSI (psi). Pounds per square inch.
What is the destination unit in this conversion?
The destination unit is the Bar (bar). A bar is exactly 100,000 pascals.
How do I convert PSI to Bar?
Multiply the PSI value by 0.0689476. For example, 10 psi × 0.0689476 = 0.689476 bar.
Is the PSI to Bar 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 PSI needs to be compared with, or reported in, Bar, such as in engineering, scientific, or industrial calculations.
Can I convert Bar back to PSI?
Yes. Multiply the Bar value by 14.5038 to get PSI.

About this conversion
This page converts PSI (psi) to Bar (bar) within the engineering converter.
Pounds per square inch. A bar is exactly 100,000 pascals.
The formula is bar = psi × 0.0689476, 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.
