Converter
1 psi = 6894.757293 Pa
How it works
This tool converts pounds per square inch to Pascals using the exact factor 1 psi = 6894.757293 Pa. If you select gauge pressure, your input is converted to absolute by adding the chosen atmospheric reference.
Formulas
Pa = psi × 6894.757293168 kPa = Pa ÷ 1000 MPa = Pa ÷ 1,000,000 If gauge: psi_eff = psi + atm_ref
Tip: Use scientific notation for very large or very small results. Adjust decimals for quick rounding.
Quick examples
- 32 psi (absolute) → 220632 Pa ≈ 220.63 kPa
- 0 psi (gauge), atm 14.6959 → 101325 Pa
- 145 psi (absolute) → 1.000 MPa
Frequently Asked Questions
One pound per square inch equals exactly 6894.757293168 Pascals. The factor traces to the pound force and the square inch definitions.
Psia is absolute pressure referenced to a perfect vacuum. Psig is gauge pressure referenced to local atmospheric pressure. To convert psig to absolute add the atmospheric reference value.
Yes. Switch to batch mode then paste values separated by new lines spaces commas or semicolons. You can download results as a CSV file.
Use fewer decimals for quick estimates and more for engineering reports. Scientific notation helps display very large or small values compactly without losing significance.
No. The PSI to Pascal conversion is purely unit based. Temperature affects gas properties but not the unit relationship.
Sea level standard is about 14.6959 psi. At elevation or unusual weather use your local atmospheric pressure for the most accurate conversion from psig to absolute.
Engineering work commonly uses SI multiples. Showing kPa and MPa beside Pa helps comparisons and ensures easy integration into reports and datasheets.
