Pressure Converter

Convert between different pressure units including Pascal, Bar, PSI, Atmosphere, Torr, and mmHg with precision and ease.

Quick Reference

Standard Atmosphere

1 atm = 101,325 Pa
1 atm = 1.01325 bar
1 atm = 14.696 PSI
1 atm = 760 mmHg

Common Conversions

1 bar = 100,000 Pa
1 hPa = 100 Pa = 1 mbar
1 MPa = 1,000,000 Pa
1 PSI = 6,895 Pa
1 Torr = 133.322 Pa
1 mmHg = 133.322 Pa

Typical Tire Pressure

Car: 30-35 PSI
Car: 2.1-2.4 bar
Bike: 80-130 PSI
Bike: 5.5-9.0 bar

About Pressure Units

Scientific Units

  • Pascal (Pa): SI base unit of pressure
  • Bar: Commonly used in meteorology and engineering
  • Atmosphere (atm): Based on average atmospheric pressure

Practical Units

  • PSI: Pounds per square inch, common in US
  • mmHg: Millimeters of mercury, used in medicine
  • Torr: Named after Torricelli, similar to mmHg
