How to convert pounds per square inch (psi) to pascal (pa)
Pressure is force per unit area. Pascals (and kPa, hPa) are SI, while bar and psi are widely used in engineering and scuba. Conversions must respect absolute vs gauge references when comparing values.
This converter calculates Pounds per square inch (psi) to Pascal (Pa) values by using the correct conversion rule for the Pressure category. For linear units, standardized factors are used. For temperature, the calculator applies the proper formula with offsets.

Conversion formula
Linear unit conversions use standardized factors; many are exact by definition (e.g., 1 in = 25.4 mm, 1 ft = 0.3048 m).
Common mistakes
- Comparing gauge pressure (psig) with absolute pressure (psia/hPa) without converting reference.
- Mixing bar with atm (1 atm = 1.01325 bar).
Unit facts
- Pounds per square inch (psi): Pounds per square inch (psi) is common for tires, hydraulics, and scuba tanks (1 psi ≈ 6,894.76 Pa).
- Pascal (Pa): Pascal (Pa) is the SI unit of pressure: 1 Pa = 1 N/m².
About Pounds per square inch (psi)
Pounds per square inch (psi)
Imperial/US pressure unit. Common for tires, hydraulics, and compressors; often shown with gauge (psig) vs absolute (psia).
History: Industrial adoption in North America entrenched psi as a practical non-SI unit.
About Pascal (Pa)
Pascal (Pa)
SI unit equal to 1 N/m². Used for stress, tire pressure (kPa), and atmospheric science (hPa).
History: Named after Blaise Pascal; became practical with digital sensors capable of stable low-pressure readings.
