Pounds per square inch to kilopascals
Type a value in psi to get it in kPa instantly.
That's 2× as much pressure as the air on Everest, while air at sea level is 1.47× higher. Spread over a fingertip, that is like resting 0.7031 kg on it.
Convert the other way: kPa to psi
What it means
How much pressure is that?
Tyre and tank figures are gauge pressure, measured above the surrounding air. Weather and altitude figures are absolute.
The math
How to convert psi to kPa
To convert pounds per square inch to kilopascals, multiply by 6.89476.
Example: 10 psi × 6.89476 = 68.9476 kPa.
In the other direction, 1 kPa = 0.145038 psi.

About these units
Pounds per square inch (psi)
One psi is one pound of force on one square inch, about 6,895 pascals. US tyre gauges, compressors and plumbing all read in psi.
Kilopascals (kPa)
A kilopascal is 1,000 pascals. Car tyres run at roughly 220 kPa, and standard air pressure is 101.3 kPa.
