🌡️ Pressure Converter
Convert between PSI, bar, atm, Pascal, and more
Quick Reference
1 atm = 101,325 Pa
1 atm = 14.696 psi
1 bar = 100,000 Pa
1 atm = 760 mmHg = 760 torr
Standard tire pressure ≈ 32 psi ≈ 2.2 bar
How Pressure Conversion Works
- 1Enter a pressure value in any supported unit.
- 2Select the source unit (PSI, bar, atm, Pa, kPa, mmHg, etc.).
- 3The converter applies the standard conversion factor.
- 4All pressure units are calculated and displayed simultaneously.
- 5Reference: 1 atm = 14.696 PSI = 1.01325 bar = 101,325 Pa.

Frequently Asked Questions
What is normal atmospheric pressure?
Standard atmospheric pressure is 1 atm = 14.696 PSI = 1.01325 bar = 101,325 Pa = 760 mmHg. This is the average pressure at sea level.
What does PSI stand for?
PSI stands for Pounds per Square Inch. It measures the force in pounds applied to one square inch of area. Common in tire pressure (32-35 PSI for most cars) and industrial applications.
How do I convert bar to PSI?
Multiply bar by 14.5038. For example, 2.5 bar = 36.26 PSI. For a quick estimate, multiply bar by 14.5.
