About Bar to PSI
Convert bar to psi instantly, with a reference table of common values. The factor is exact: 1 bar = 14.503773773 psi.
The conversion for using a psi-calibrated gauge against a specification in bar, which is the usual situation with imported equipment and diving gear.
The bar was defined deliberately as 100,000 pascals, which makes it very close to average atmospheric pressure at sea level. That closeness is the point โ it puts everyday pressures near a value of 1. It is common in European engineering, meteorology in its millibar form, and diving, where each 10 metres of depth adds roughly one bar. One bar is about 14.5 psi, and sea-level atmospheric pressure is roughly 1.013 bar.
Worked through with real numbers: 1 bar is 14.504 psi, 15 bar is 217.557 psi, 30 bar is 435.113 psi.
As for the other side of the conversion: car tyres are typically inflated to 30 to 35 psi, and atmospheric pressure at sea level is about 14.7 psi.
Pressure is force divided by area, so every pressure unit combines two other units. The values cluster near everyday atmospheric pressure โ about 14.7 psi, 1.013 bar or 101.3 kPa โ because most practical scales were built around it.

Frequently asked questions
How do I convert bar to psi?
Multiply your bar figure by 14.503773773 to get psi โ or type a value above and read the answer straight off.
How many psi are in one bar?
1 bar = 14.503773773 psi.
When would I need to convert bar to psi?
The conversion for using a psi-calibrated gauge against a specification in bar, which is the usual situation with imported equipment and diving gear.
What is a bar, exactly?
The bar was defined deliberately as 100,000 pascals, which makes it very close to average atmospheric pressure at sea level. That closeness is the point โ it puts everyday pressures near a value of 1. One bar is about 14.5 psi, and sea-level atmospheric pressure is roughly 1.013 bar.
Where is the psi actually used?
It is the standard for tyre pressure, hydraulics and compressed gas in the United States, and appears on tyre gauges worldwide. Car tyres are typically inflated to 30 to 35 psi, and atmospheric pressure at sea level is about 14.7 psi.
Is there anything tricky about pressure conversions?
Pressure is force divided by area, so every pressure unit combines two other units. The values cluster near everyday atmospheric pressure โ about 14.7 psi, 1.013 bar or 101.3 kPa โ because most practical scales were built around it.
Is this converter accurate?
Yes. It uses the exact standard factor of 1 bar = 14.503773773 psi, and the conversion runs in your browser so nothing is uploaded.
