Pascal to PSI Conversion - Free Pa ⇄ psi Calculator
Convert between Pascals (Pa) and pounds per square inch (PSI) with precision using standard pressure measurements
Pressure is one of the most important physical quantities in engineering, physics, and daily applications. Two of the most commonly used pressure units are Pascal (Pa) and pounds per square inch (psi). Pascal is part of the metric SI system, while psi belongs to the imperial/US customary system.
Understanding how to perform a pascal to psi conversion or the reverse (psi to pascal) is crucial in fluid mechanics, hydraulics, automotive, and industrial systems.Our pascal ⇄ psi converter makes this process simple and precise.

What is a Pascal (Pa)?
The pascal (Pa) is the SI unit of pressure. It measures force per unit area.
Key Facts About Pascal
- Exact definition: 1 Pa = 1 newton per square meter (1 N/m²).
- Abbreviation: Pa.
- Relationship: 1 kilopascal (kPa) = 1000 Pa.
- Usage: Fluid mechanics, material science, meteorology, and engineering.
What is PSI (pounds per square inch)?
PSI (pounds per square inch) is an imperial unit of pressure. It measures force (in pounds) applied over an area of one square inch.
Key Facts About PSI
- Exact definition: 1 psi = 6894.76 Pa.
- Abbreviation: psi.
- Relationship: Commonly used in tires, hydraulics, and pipelines.
- Usage: Automotive, aerospace, industrial equipment, and HVAC systems.
Pascal to PSI Conversion Formula
Formula:
psi = Pa ÷ 6894.76
Pascal to PSI Conversion Example
- 100,000 Pa to psi
Step 1: Formula = psi = Pa ÷ 6894.76
Step 2: Substitute = 100,000 ÷ 6894.76
Step 3: Result = 14.50 psi
- 500,000 Pa to psi
Step 1: psi = Pa ÷ 6894.76
Step 2: Substitute = 500,000 ÷ 6894.76
Step 3: Result = 72.52 psi
- 1,000,000 Pa to psi
Step 1: psi = Pa ÷ 6894.76
Step 2: Substitute = 1,000,000 ÷ 6894.76
Step 3: Result = 145.04 psi
PSI to Pascal Conversion Formula
Formula:
Pa = psi × 6894.76
PSI to Pascal Conversion Example
- 1 psi to Pa
Step 1: Formula = Pa = psi × 6894.76
Step 2: Substitute = 1 × 6894.76
Step 3: Result = 6894.76 Pa
- 50 psi to Pa
Step 1: Pa = psi × 6894.76
Step 2: Substitute = 50 × 6894.76
Step 3: Result = 344,738 Pa
- 100 psi to Pa
Step 1: Pa = psi × 6894.76
Step 2: Substitute = 100 × 6894.76
Step 3: Result = 689,476 Pa
Applications of Pascal and PSI Conversion
- Automotive: Tire pressures are often given in psi, but research may require pascals.
- Engineering & Hydraulics: Pressure gauges and fluid systems use both units.
- Meteorology: Atmospheric pressure is measured in pascals but sometimes converted to psi.
- HVAC Systems: Heating, ventilation, and cooling require psi and pascal readings.
- Industrial Equipment: Compressors, pumps, and pipelines are rated in psi and Pa.
