About the Pascal
Pascal (Pa) is a unit of pressure measurement. 1 pascal is equal to 0.0001450 psi.
Pressure Units Across Industries
Pressure measurements vary dramatically by industry. Meteorologists report in millibars or hectopascals, tire shops use PSI, scuba divers think in atmospheres or bar, vacuum engineers work in torr, and hydraulic systems specify in megapascals. A single industrial plant might encounter all these units across different equipment manuals, safety datasheets, and regulatory standards from different countries.

Solved Examples: PSI to Pascal
Question 1: A CFD simulation requires boundary conditions in pascals. The wind tunnel test measured 2.5 PSI dynamic pressure. Convert to Pa.
Solution:
Pressure in Pa = 2.5 × 6894.76
= 17,236.9 Pa
= 17.24 kPa
Answer: 2.5 PSI = 17,237 Pa (17.24 kPa) — a typical dynamic pressure at Mach 0.3.
Question 2: An aerospace component is rated to withstand 150 PSI cabin differential pressure. Express in pascals for the design report.
Solution:
Pressure in Pa = 150 × 6894.76
= 1,034,214 Pa
= 1.034 MPa
Answer: 150 PSI = 1,034,214 Pa ≈ 1.03 MPa — standard fuselage differential pressure at cruise altitude.
Question 3: A rocket engine chamber pressure is 1000 PSI. Convert to pascals for thrust calculation.
Solution:
Pressure in Pa = 1000 × 6894.76
= 6,894,760 Pa
= 6.895 MPa
Answer: 1000 PSI = 6,894,760 Pa ≈ 6.9 MPa chamber pressure.
Question 4: Blood pressure is 120 mmHg systolic. A US medical device reads 2.32 PSI. Confirm in pascals.
Solution:
Pressure in Pa = 2.32 × 6894.76
= 15,995.8 Pa
= 16.0 kPa
Cross-check: 120 mmHg × 133.322 = 15,999 Pa ✓
Answer: 2.32 PSI = 15,996 Pa (16.0 kPa) — matches 120 mmHg systolic blood pressure.

Aerospace Engineering: Why Pascals Matter
Aerospace engineering operates at the intersection of US customary (PSI, lbf) and SI (Pa, N) units. NASA and ESA both use SI internally, but legacy systems and subcontractors often provide data in PSI. Cabin pressure differential (typically 8-9 PSI = 55,000-62,000 Pa), aerodynamic loads, and propulsion chamber pressures must all be expressed in pascals for finite element analysis (FEA) and computational fluid dynamics (CFD) software that operate in SI units.
Scientific Publications: SI Unit Requirements
Most scientific journals (Nature, Science, AIAA, ASME) require SI units. A pressure of "500 PSI" must appear as "3.45 MPa" or "3,447 kPa" in manuscripts. Supplementary information may include original PSI values. When converting experimental data from US-made instruments (pressure transducers calibrated in PSI) to pascals for publication, maintain significant figures: 500.0 PSI = 3,447,379 Pa should be reported as 3.447 MPa (4 significant figures matching the original measurement).
PSI to Pa in Fluid Dynamics Calculations
Bernoulli's equation and Navier-Stokes equations require consistent SI units. When experimental data arrives in PSI (common from US wind tunnels and test rigs), converting to pascals ensures dimensional consistency: dynamic pressure q = ½ρv² yields Pa when density is in kg/m³ and velocity in m/s. A pitot tube reading of 0.5 PSI corresponds to 3,447 Pa dynamic pressure, which at sea-level density (1.225 kg/m³) implies airspeed of ~75 m/s (145 knots).
Key Takeaways
- 1 PSI = 6894.76 Pa — multiply PSI by ~6895 for pascals.
- Standard atmosphere: 14.696 PSI = 101,325 Pa exactly.
- Scientific journals require SI units (Pa, kPa, or MPa).
- Aerospace CFD and FEA simulations need input in pascals.
- Maintain proper significant figures when converting experimental PSI data.
- 1 PSI ≈ 6.9 kPa ≈ 0.0069 MPa for quick mental conversion.
