Convert Kilopascals to Pounds per square inch
1 kilopascal is 0.145038 psi. One kilopascal is exactly 0.14503773773 pounds per square inch.
One kilopascal is 0.14503774 pounds per square inch. To convert kilopascals to pounds per square inch, multiply by 0.14503774; to go the other way, divide by 0.14503774 or multiply by 6.8947573. The factor is exact rather than rounded: it follows from NIST Special Publication 811. A thousand pascals, and the unit metric tyre placards and weather stations use.

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.
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.
How many pounds per square inch are in a kilopascal?
One kilopascal is 0.14503774 pounds per square inch. Going the other way, one pound per square inch is 6.8947573 kilopascals. 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.
