kPa to psi: Convert kilopascals to psi

Answer
0.145038 psi = 1 kPa

1 kPa = 0.145038 psi. To convert kilopascals to psi, multiply by 0.1450377377. To go back, multiply by 6.894757293 (or divide by 0.1450377377). Kilopascals appear on tire placards next to psi and in technical standards; 100 kPa = 1 bar.
