Answer
Pascals to bar
1 pascal equals 0.00001 bar. 1 bar equals 100,000 pascals. The formula is bar = Pa ÷ 100000.
bar = Pa ÷ 100000
| Pascals | Bar |
|---|---|
| 1 Pa | 0.00001 bar |
| 100 Pa | 0.001 bar |
| 1,000 Pa | 0.01 bar |
| 10,000 Pa | 0.1 bar |
| 100,000 Pa | 1 bar |
| 101,325 Pa (1 atm) | 1.01325 bar |
| 1,000,000 Pa | 10 bar |
Common questions
What is 1 pascal in bar?

Pressure conversion reference table
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.

How to use this pressure converter
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.
What to check
- Confirm whether the source value is gauge pressure or absolute pressure before comparing readings.
- Bar and millibar are decimal units; PSI is pounds-force per square inch.
- Use the reference table for common values, then keep extra precision until the final reported result.
Quick answers
How do I convert PSI to bar?
Multiply PSI by 0.0689476. For example, 30 PSI is about 2.06843 bar.
How many pascals are in one bar?
One bar equals exactly 100,000 pascals, or 100 kilopascals.
How many PSI are in one atmosphere?
One standard atmosphere is about 14.6959 PSI.
Which pressure unit should I use?
Weather reports commonly use hectopascals or millibars, tire pressure often uses PSI or bar, and engineering calculations commonly use pascals or kilopascals.
