Bars to Psi
A bar is close to average atmospheric pressure at sea level, widely used for tire pressure and industrial gauges in Europe. Pounds per square inch is the standard pressure unit for tire inflation and plumbing in the US. 1 bar equals ≈14.5038 psi, so converting between them is a matter of multiplying by that fixed factor — type any value into the converter below and both sides update instantly as you type.
Both units belong to pressure, measured here against pressure's base unit (Pa) — every other pressure unit on this site converts through that same reference point, which is why the table below can also be read as a quick cross-check against nearby values.
Formula
psi = bar × ≈14.5038
bar = psi × ≈0.0689476
Worked example: 5 bar × ≈14.5038 = ≈72.5189 psi.

Frequently asked
- How many PSI in a bar?
- 1 bar equals ≈14.5038 psi.
- How do I convert Bars to PSI?
- Multiply the value in bar by ≈14.5038 to get psi. The converter above does this instantly as you type.
- Is the conversion exact?
- Yes — Bar and PSI are both defined by a fixed conversion factor to pressure's base unit (Pa), so the result shown is exact to the precision displayed, not an approximation.
