Pressure Converter
Convert between Pascal, Bar, PSI, atm, and Torr.
Effective atmosphere: 101325.00 Pa
atm → psi
1 atm × 101325 = 101325 Pa; 101325 Pa ÷ 6894.75729316836 = 14.695948775513452 psi

Common pressure conversions
- 1 bar = 100 kPa = 14.5038 psi = 750.062 Torr
- 1 atm = 101325 Pa = 1.01325 bar = 14.6959 psi = 760 Torr
- 1 psi = 6894.757 Pa = 68.9476 mbar = 51.7149 mmHg
- 1 kgf/cm² = 98066.5 Pa = 14.2233 psi = 0.980665 bar
- psig = psia − 14.6959 psi (at standard atmosphere)
