How do I convert PSI to bar?
Multiply PSI by 0.0689476. For example, 30 PSI is about 2.06843 bar.
Convert pascals, bar, PSI, atmospheres, torr, and other pressure units accurately.
Convert pressure units used in science, weather, engineering, and tires. Use OmniUnit for fast conversions between common units without leaving the page.
Each row converts one unit into the column units using the same factors as the calculator. Values are rounded to six significant digits. Pa means pascal, psi means pound per square inch, and atm means standard atmosphere. Torr and mmHg are separate units in this calculator.

Compare readings on the same basis: this table converts units but does not change gauge pressure to absolute pressure.
Convert pressure values between pascals, kilopascals, bar, PSI, atmospheres, torr, and other common units. OmniUnit uses the stored conversion factor for each unit and rounds only the displayed result.
Multiply PSI by 0.0689476. For example, 30 PSI is about 2.06843 bar.
One bar equals exactly 100,000 pascals, or 100 kilopascals.
One standard atmosphere is about 14.6959 PSI.
Weather reports commonly use hectopascals or millibars, tire pressure often uses PSI or bar, and engineering calculations commonly use pascals or kilopascals.
