About converting PSI to Pascals
PSI (psi) and Pascals (Pa) are both units of pressure, so converting between them is a single multiplication: multiply your PSI figure by 6,894.76. Ten PSI comes to 68,947.57 Pascals, and a hundred works out at 689,475.73 Pascals.
Rule of thumb: going from PSI to Pascals multiplies, so the figure always grows — one PSI is already 6,894.76 Pascals. If your answer came out smaller, you have the conversion the wrong way round.
What is a PSI?
Pounds per square inch is the pressure unit Americans actually meet: on the gauge at the filling-station air pump, on compressors, on hydraulic equipment, and on the sidewall of every tyre sold in the country. It survives in British tyre pressures too, despite nearly everything else there having gone metric. Structurally it is exactly what the name says — a pound-force resting on a square inch — and that heritage is also its weakness, because it inherits the pound-force and with it the old confusion between pounds as weight and pounds as mass.
What is a Pascal?
The pascal is the SI unit of pressure: one newton spread over one square metre. It is named after Blaise Pascal, who established that air pressure falls with altitude by having a barometer carried up a mountain. The awkward thing about the unit is its scale — a single pascal is a very small pressure indeed, so honest real-world figures come out enormous, atmospheric pressure alone being about 101,325 of them. That is why hardly anyone works in bare pascals: engineers reach for kilopascals, meteorologists for hectopascals, and industry for the bar.
To put both in perspective: a car tyre is usually inflated to about 32 psi, while sea-level air pressure is about 101,325 pascals.

Frequently asked questions
How many Pascals are in one PSI?
There are 6,894.76 Pascals in one PSI.
How do I convert PSI to Pascals?
Multiply the number of PSI by 6,894.76. For example, 10 PSI = 68,947.57 Pascals.
What is 100 PSI in Pascals?
100 PSI is equal to 689,475.73 Pascals.
How do I convert Pascals to PSI?
Multiply the Pascals value by 0.000145 (or divide by 6,894.76).
Is this PSI to Pascals conversion exact?
The definition is exact — PSI and Pascals are both fixed against the same base by international agreement — but the decimal shown here is rounded for readability, because the true ratio does not terminate. For engineering or scientific work, carry more decimal places than this page displays.
