Enter a value to instantly convert between pressure units.
1 Pascal = 0.0001 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 = Pa ÷ 6894.76One pound-force per square inch equals 6894.76 pascals by definition, derived from 1 psi = 1 lbf/in² = 4.44822 newtons ÷ 0.00064516 square meters. PSI is the dominant pressure unit in North American automotive, hydraulic, and industrial applications. Converting pascals to PSI is critical for understanding equipment specifications and comparing international versus US-market equipment.
