About PSI to Bar
Convert psi to bar instantly, with a reference table of common values. The factor is exact: 1 psi = 0.068947573 bar.
Needed when a US-specified pressure has to be set on European equipment, which is calibrated in bar โ most commonly tyre inflation and compressed air.
Pounds per square inch expresses pressure as force divided by area, using imperial units for both. It is not an SI unit but remains deeply entrenched in industry. 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.
Worked through with real numbers: 1 psi is 0.068948 bar, 15 psi is 1.034 bar, 30 psi is 2.068 bar.
As for the other side of the conversion: one bar is about 14.5 psi, and sea-level atmospheric pressure is roughly 1.013 bar.
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 psi to bar?
Multiply your psi figure by 0.068947573 to get bar โ or type a value above and read the answer straight off.
How many bar are in one psi?
1 psi = 0.068947573 bar.
When would I need to convert psi to bar?
Needed when a US-specified pressure has to be set on European equipment, which is calibrated in bar โ most commonly tyre inflation and compressed air.
What is a psi, exactly?
Pounds per square inch expresses pressure as force divided by area, using imperial units for both. It is not an SI unit but remains deeply entrenched in industry. Car tyres are typically inflated to 30 to 35 psi, and atmospheric pressure at sea level is about 14.7 psi.
Where is the bar actually used?
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.
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 psi = 0.068947573 bar, and the conversion runs in your browser so nothing is uploaded.
