Convert Pounds per square inch to Pascals
1 pound per square inch is 6,894.757293 Pa. One pound per square inch is exactly 6894.75729317 pascals.
One pound per square inch is 6894.7573 pascals. To convert pounds per square inch to pascals, multiply by 6894.7573; to go the other way, divide by 6894.7573 or multiply by 1.4504 × 10^-4. 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 pascal?
The SI unit: one newton spread over one square metre. It is a small pressure — a sheet of paper resting on a table is about one pascal — which is why the kilopascal is what instruments actually read.
How many pascals are in a pound per square inch?
One pound per square inch is 6894.7573 pascals. Going the other way, one pascal is 1.4504 × 10^-4 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.
