Convert PSI to Pascal
Convert PSI to Pascals for SI calculations in hydraulics, pneumatics, and HVAC with the exact 6,894.76 factor.
How to Convert Psi to Pascal
To convert PSI to Pascal, multiply psi by 6,894.76 because 1 psi = 6,894.76 Pa.
Conversion Formula:
value * 6894.76Understanding the Conversion
PSI to Pascal converts Imperial pressures into the SI base unit. Multiply psi by 6,894.76 to get Pascals. This is required when performing scientific or engineering calculations that standardize on SI, or when feeding data into systems that accept Pa.
For example, 32 psi ≈ 220,632 Pa (about 220.6 kPa), and 14.7 psi ≈ 101,352 Pa (about one atmosphere). Using Pascals ensures compatibility with SI equations and sensor interfaces. The conversion is exact and reversible—divide by 6,894.76 to return to psi.
Conversion Examples
Example: Convert 32 psi to Pa
- Step 1: 32 × 6,894.76 = 220,632.32.
- Step 2: Result ≈ 220,632 Pa.
- Step 3: Reflects typical tire pressure in Pa.
32 psi ≈ 220,632 Pa

Example: Convert 14.7 psi to Pa
- Step 1: 14.7 × 6,894.76 ≈ 101,352.
- Step 2: Result ≈ 101,352 Pa.
- Step 3: Atmospheric reference.
14.7 psi ≈ 101,352 Pa
Sea-level atmosphere.
Example: Convert 100 psi to Pa
- Step 1: 100 × 6,894.76 = 689,476.
- Step 2: Result = 689,476 Pa.
- Step 3: High-pressure example.
100 psi = 689,476 Pa
Industrial or hydraulic range.
Conversion Formula
PSI is defined over square inches with pound-force; converting to Pascals scales by 6,894.76 to reach SI newtons per square meter.

Unit Definitions
Pound per Square Inch (psi)
Imperial pressure unit.
1 psi = 6,894.76 Pa = 6.89476 kPa = 0.0689476 bar.
Pascal (Pa)
SI base pressure unit.
Pa to psi divide by 6,894.76; Pa to kPa divide by 1,000.
Common Use Cases
- Hydraulics/pneumatics: convert psi readings to Pa for SI models.
- Automotive: express tire pressures in Pascals or kPa.
- HVAC: integrate psi gauges with SI-based controls.
- Research: standardize datasets in Pascals.
- QA/compliance: provide SI values alongside psi specs.
