Psi to Pascals
Pounds per square inch is the standard pressure unit for tire inflation and plumbing in the US. The pascal is the SI unit of pressure, defined as one newton per square meter, used in scientific and engineering contexts. 1 psi equals ≈6,894.76 Pa, so converting between them is a matter of multiplying by that fixed factor — type any value into the converter below and both sides update instantly as you type.
Both units belong to pressure, measured here against pressure's base unit (Pa) — every other pressure unit on this site converts through that same reference point, which is why the table below can also be read as a quick cross-check against nearby values.
Formula
Pa = psi × ≈6,894.76
psi = Pa × ≈0.000145038
Worked example: 5 psi × ≈6,894.76 = ≈34,473.8 Pa.

Frequently asked
- How many Pascals in a psi?
- 1 psi equals ≈6,894.76 Pa.
- How do I convert PSI to Pascals?
- Multiply the value in psi by ≈6,894.76 to get Pa. The converter above does this instantly as you type.
- Is the conversion exact?
- Yes — PSI and Pascal are both defined by a fixed conversion factor to pressure's base unit (Pa), so the result shown is exact to the precision displayed, not an approximation.
