Convert Pounds per square inch to Kilopascals
1 pound per square inch is 6.894757 kPa. One pound per square inch is exactly 6.89475729317 kilopascals.
One pound per square inch is 6.8947573 kilopascals. To convert pounds per square inch to kilopascals, multiply by 6.8947573; to go the other way, divide by 6.8947573 or multiply by 0.14503774. The factor is exact rather than rounded: it follows from NIST Special Publication 811. A pound-force spread over a square inch.

What is a pound per square inch?
A pound-force spread over a square inch. Exact, because both parts are: it is 4.4482216152605 newtons divided by an inch squared. Every US tyre gauge, air line and pressure washer is marked in it.
What is a kilopascal?
A thousand pascals, and the unit metric tyre placards and weather stations use. Atmospheric pressure at sea level is about 101 kPa.
How many kilopascals are in a pound per square inch?
One pound per square inch is 6.8947573 kilopascals. Going the other way, one kilopascal is 0.14503774 pounds per square inch. Both figures come from the same defined relation rather than from a measurement, which is why they are the same today as they were in 1959.
