How to Convert psi to Pascal
- 1 psi = 6894.757293 Pa
- 1 Pa = 0.0001450377377 psi
- Example: convert 15 psi to Pa: 15 psi = 15 × 6894.757293 Pa = 103421.3594 Pa
Formula
Pa = psi × 6894.757293168
Derivation from SI units:
- 1 psi = 1 lbf/in² = (0.45359237 kg × 9.80665 m/s²) ÷ (0.0254 m)² = 6894.757293168 Pa
- 1 Pa = 1 N/m² = 1 kg·m⁻¹·s⁻²
Both units are defined exactly, so the factor is exact. psi definition: psi; Pascal definition: pascal.
Worked examples
- Sea-level atmospheric pressure, about 14.7 psi, is 101352.9322 Pa.
14.7 psi × 6894.757293 = 101352.9322 Pa - A compressed-air line at 90 psi gauge is 620528.1564 Pa above atmospheric pressure.
90 psi × 6894.757293 = 620528.1564 Pa

Where it's used
Converting psi to pascals is the first step when US datasheet values go into SI formulas such as ΔP = ρ·g·h or the ideal gas law, where the pascal is the coherent unit. The result is usually re-expressed in kPa or MPa for readability.

Frequently asked questions
Why is 1 psi not a round number of pascals?
Because psi is built from the pound (0.45359237 kg), standard gravity (9.80665 m/s²) and the inch (0.0254 m). The product is exact, 6894.757293168 Pa, but not round.
How many pascals are in 1 psi?
1 psi = 6894.757293 Pa.
How do I convert psi to pascals?
Multiply the value in psi by 6894.757293. For example, 15 psi × 6894.757293 = 103421.3594 Pa.
Is the psi to Pa conversion exact?
Yes. Both units are defined exactly, so the ratio is exact; its decimal form does not terminate and is shown here to 10 significant figures (more with the precision selector).
