- 100 Kilopascals (kPa) = 14.503774 Pounds per square inch (psi)
Convert kilopascals to psi, the swap you need for tire pressures and gauges when one reads in kPa and the other in psi. Enter the kilopascals and read the psi, and swap to convert psi back to kPa.
How this is calculated
One psi is 0.45359237 times 9.80665 divided by 0.0254 squared pascals, about 6894.757 Pa, so one kilopascal is about 0.145038 psi. The tool converts through pascals using these exact SI-based definitions.
How to use
- Enter the pressure in kilopascals.
- Keep kPa to psi, or press Swap for the reverse.
- Read the result in psi.
Examples
- Around one bar:
100 kPa = 14.503774 psi - A car tire:
220 kPa = 31.907702 psi
FAQ
- How many psi is 100 kPa?
- About 14.5 psi, which is close to one atmosphere of pressure.
- Why do tire pressures use kPa and psi?
- Vehicle stickers vary by region. Many use kPa or bar while US gauges use psi, so a quick conversion helps.
