Why this conversion is exact
The exact factor behind this page: 1 psi = 0.0689476 bar. That value is a defined standard, not a measurement, so every conversion on this page is exact up to the digits shown. The most common practical error is mixing up which direction the factor runs: multiply when going from psi to bar, divide when returning.
Rounding is display-only. The converter keeps full precision internally, so chained conversions (this unit to another and back) return to the starting value without drift, which hand-rounded tables cannot promise.
