What Are Psi to Kilopascals Using?
Psi to kilopascals multiply by 6.894757. One psi is 6.894757 kilopascals. Forty psi is 275.790280 kilopascals at six decimals. The result is a pressure label. It does not say a switch is set, a tank is charged, or a pump will make the flow.
Quick Answer
Psi to kilopascals use 6.894757, the NIST Appendix B.8 line printed as 6.894 757 E+00. One psi is 6.894757 kilopascals. Sixty psi is 413.685420 kilopascals at six decimals. The factor is not called exact. Feet of head are a different conversion.
One factor, both directions
The NIST table prints 6.894 757 in the multiply-by column and E+00 in the exponent column. Read together, that is 6.894757 kilopascals in one psi. This page uses 6.894757 so a psi reading round-trips through kilopascals. It does not build the result from feet of head.
One kilopascal divided by 6.894757 is the reverse psi count, shown at six decimals on the worked table. The engine divided by 6.894757. It did not use 2.31.
Common psi readings
Each row multiplies by 6.894757 and shows 6 decimal places. These are not recommended cut-in or cut-out settings.

Worked examples
One psi is 6.894757 kilopascals. Forty psi is 275.790280 kilopascals. Sixty psi is 413.685420 kilopascals at six decimals. The reverse of one kilopascal divides by 6.894757.
| Case | Psi | Kilopascals |
|---|---|---|
| 1 psi | 1.000000 | 6.894757 |
| 40 psi | 40.000000 | 275.790280 |
| 60 psi | 60.000000 | 413.685420 |
| 1 kilopascal | 0.145038 | 1.000000 |
Psi is not feet of head
Feet of head stated as psi, using 2.31, stay on feet of head to psi. A pump horsepower estimate stays on well pump size. This page has no 2.31 and no horsepower.
How should you write psi to kilopascals?
Write five lines before the number leaves this page. A later visit should not have to guess which gauge was used.
- The entered value, and whether it was psi or kilopascals.
- The factor, 6.894757, named as the NIST line.
- Both results, at 6 decimals.
- Which gauge, log, or sheet the pressure came from.
- A note that feet of head and the pascal row were not applied, and that the factor was not called exact.
What stays off this pressure
Multiplying by 1,000 to reach pascals is not how this page reads the kilopascal row. The NIST page prints that pascal row separately. This tool does not use it.
A water treatment dealer who saves the 6.894757 note will not swap in feet of head. This conversion does not size a pressure tank and does not say a sample passed a county rule. A private-well lab sheet is still the well water testing guide. Static pressure on a duct stays on the static pressure calculator.
A gauge that already reads in kilopascals does not need this page to invent a second factor. Divide by 6.894757 to see the psi. A gauge that reads in psi multiplies by 6.894757 to see the kilopascals. Either way the note names the NIST row. It does not say the reading passed a code, and it does not replace the manufacturer curve on a pump.
Frequently Asked Questions
How do psi to kilopascals use 6.894757?
Multiply pounds per square inch by 6.894757. That is the NIST Appendix B.8 row for psi into kilopascals, printed as 6.894 757 E+00. Divide kilopascals by the same factor to go back. The factor is not called exact, because boldface was not preserved.
Is 6.894757 a feet-of-head factor?
No. Feet of head stated as psi stay on the feet of head to psi converter, which uses 2.31. This psi to kilopascals tool does not use 2.31, and it does not use the NIST foot-of-water row.
Does this page convert psi to pascals?
No. The same NIST page also prints a psi row into pascals, 6.894 757 E+03. This page uses the kilopascal row only, 6.894 757 E+00. It does not multiply by 1,000 on its own.
What is one psi in kilopascals?
One psi is 6.894757 kilopascals. Forty psi is 275.790280 kilopascals. Sixty psi is 413.685420 kilopascals at six decimals. Those products use the printed NIST factor.
