Kilopascals (kPa) to Pounds per Square Inch (psi) Converter
Enter a value to instantly convert between pressure units.
1 Kilopascal = 0.145 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 = kPa × 0.145038A kilopascal equals 0.145 psi — since 1 psi = 6894.76 Pa and 1 kPa = 1000 Pa, then 1000 ÷ 6894.76 = 0.145. Use it when a metric specification must be compared with a psi gauge. For example, 200 kPa ≈ 29 psi and 7,000 kPa ≈ 1,015 psi.
