Pressure Converter
Pressure is force per unit area. The SI unit is the pascal (Pa), one newton per square metre. Standard atmospheric pressure is defined as 101,325 Pa, the bar is exactly 100,000 Pa, and pounds per square inch (psi) remain common in the United States.
1 Kilopascal = 0.1450377377 PSI
How to convert Kilopascal to PSI
One Kilopascal equals 0.1450377377 PSI, so multiply any value in kPa by 0.1450377377 to get psi. To convert back, divide by 0.1450377377 — or multiply by 6.894757293.
psi = kPa × 0.1450377377
Example: 25 kPa × 0.1450377377 = 3.625943443 psi.
