To convert kilopounds per square inch to pascals, multiply by 6,894,757.293. That factor is the whole relationship: both units measure pressure, so the conversion is a proportion with no offset and no substance-specific constant.
The SI unit: one newton per square metre. One thousand psi; the unit US steel and alloy strengths are quoted in.
Gauge versus absolute. A tyre gauge reading 32 psi means 32 psi above atmospheric, which is about 46.7 psi absolute. Converting the number is straightforward; remembering which zero it was measured from is where the mistakes happen. N/mm² and MPa are the same size, so a drawing quoting either is quoting the same stress. The tables underneath give both a plain step-by-step lookup and a list of real quantities expressed in pascals, so you can sanity-check whether your answer is a plausible size.

Worked examples
A bicycle tyre: 0.09 ksi in pascals
A bicycle tyre comes to about 0.09 ksi. Multiplying by the factor: 0.09 × 6.89476e+06 = 620,528 Pa. Dividing the answer back by 6.89476e+06 returns the figure you started with, which is the quickest way to check you have the factor the right way up.
Blood pressure, systolic: 0.00232 ksi in pascals
At 0.00232 ksi (blood pressure, systolic), the same quantity in pascals is 0.00232 × 6.89476e+06 = 15,995.8 Pa. One kilopound per square inch is 6.89476e+06 pascals, so the numbers grow as expected.

Frequently asked questions
How many pascals are in one kilopound per square inch?
Exactly 6,894,757.29317. Every figure on this page is that one number multiplied by your input, so the only rounding is at the display step.
What is the formula to convert kilopounds per square inch to pascals?
pascals = kilopounds per square inch × 6,894,757.29317. Reversed, kilopounds per square inch = pascals ÷ 6,894,757.29317, which is the same as multiplying by 1.4503773773e-07.
Which is the bigger unit, the kilopound per square inch or the pascal?
The kilopound per square inch. One kilopound per square inch equals 6.89476e+06 pascals.
What does this quantity actually measure?
Both units measure pressure. That is why a single factor is enough: there is no temperature offset and no material property involved, unlike conversions that cross between different quantities.
What is a kilopound per square inch?
One thousand psi; the unit US steel and alloy strengths are quoted in.
What is a pascal?
The SI unit: one newton per square metre.
Why does my answer differ from another converter?
Almost always because the other tool rounded the factor before multiplying. This page keeps full double precision through the calculation and rounds only for display, and it prints the factor it used so you can see where any difference came from.
Is there a quick way to do ksi to Pa in my head?
Plenty of people do this in their head: multiply by 7000000.000000 instead of using the exact factor 6,894,757.293. At 100 that shortcut gives 700000000.000000 pascals, off by 10524270.683200 pascals or about 1.53%. Fine for a rough estimate, not fine for anything you are cutting to size or dosing.
