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
Pa = torr × 133.322One torr equals 133.322 pascals. Torr is historically based on atmospheric pressure at sea level (1 atm = 760 torr = 101,325 Pa). Vacuum scientists and laboratory technicians use torr to specify chamber pressures during experiments, thin-film deposition, and evaporation processes. Converting to pascals gives the SI unit for technical specifications.
