About Converting Kilopascals to KSI
Kilopascal and KSI both show up on pressure gauges — psi is standard on US tire and tool specifications, while bar is the everyday pressure unit across most of the rest of the world. Specifically: Kilopascal is 1000 pascal units, and kips per square inch.
Formula
ksi = kilopascals × 0.00014503773773
This factor comes from each unit's defined relationship to the category's base unit: 1 kilopascal equals 1000 base units, and 1 ksi equals 6894757.29317 base units, so dividing one by the other gives the direct kilopascal-to-ksi factor of 0.00014503773773.
Simple example
1 kPa × 0.0001450377377 = 0.0001450377 ksi
1 kilopascal = 0.0001450377 ksi.
Real-world example
35 kPa × 0.0001450377377 = 0.0050763208 ksi
35 kilopascals = 0.0050763208 ksi.

How do I convert ksi back to kilopascal?
Use the reverse factor: 1 ksi equals 6,894.757293 kilopascals. You can also use the swap control in the converter above to flip the direction instantly.
What is a kilopascal?
Kilopascal (kPa) is a unit of pressure.
What is a ksi?
KSI (ksi) is a unit of pressure.
Is the kilopascal to ksi conversion exact?
Yes. Both kilopascal and ksi are defined by fixed standards rather than physical artifacts, so the factor of 0.0001450377377 used above is exact to as many digits as you choose to display.
