Torr to PSI Converter
Enter a value to instantly convert between pressure units.
1 Torr = 0.0193 Pound per Sq. Inch
Key Formulas
Pound per Sq. Inch → Bar
bar = psi × 0.0689476Bar → Pound per Sq. Inch
psi = bar × 14.5038Atmosphere → Pound per Sq. Inch
psi = atm × 14.6959Pound per Sq. Inch → Atmosphere
atm = psi × 0.068046Formula
psi = torr × 0.01933677One torr equals 0.01933677 psi. This conversion bridges two pressure worlds: torr is the standard unit in vacuum science and laboratory settings, while psi dominates North American industrial applications. Since 760 torr = 1 atm = 14.696 psi, understanding this conversion is essential when working with vacuum systems in engineering or physics labs.
