How to Convert PSI to Pascals
To convert psi to pascals, multiply the pressure by the following conversion ratio: 6,894.7572932 pascals/pounds per square inch.
Since one pounds per square inch is equal to 6,894.7572932 pascals, you can use this simple formula to convert:
The pressure in pascals is equal to the pressure in psi multiplied by 6,894.7572932.
For example, here's how to convert 5 psi to pascals using the formula above.
How Many Pascals Are in a Pounds per Square Inch?
There are 6,894.7572932 pascals in a pounds per square inch, which is why we use this value in the formula above.

What Is a Pounds per Square Inch?
A pounds per square inch is a unit of pressure equal to 6,894.7572932 pascals (Pa), the base unit for pressure. Imperial & US pressure unit equal to 1 pound-force per square inch (6.89476 kPa). [1]
The pounds per square inch is classified as a US customary and imperial unit of pressure. PSI can be abbreviated as psi; for example, 1 pounds per square inch can be written as 1 psi.
When working with psi (psi) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, psi (psi) are widely used across large-scale industrial, bulk, and macro-level pressure specifications within US customary and imperial workflows, engineering documentation, and technical data sheets.
What Is a Pascal?
SI derived unit of pressure equal to 1 Newton per square meter (N/m²). It serves as a primary reference unit for measuring pressure across scientific and practical applications. [2]
The pascal is classified as an International System of Units (SI) unit of pressure. Pascals can be abbreviated as Pa; for example, 1 pascal can be written as 1 Pa.
As the primary coherent reference unit for pressure in this category, all other pressure units are mathematically anchored to the pascal (Pa).
In practice, pascals (Pa) are widely used across standard pressure applications within International System of Units (SI) workflows, engineering documentation, and technical data sheets.
When converting pressure between psi (psi) and pascals (Pa), keep full floating-point precision (1 psi = 6,894.7572932 Pa; 1 Pa = 0.000145038 psi) during intermediate calculations and round only the final pascal figure to match your instrument tolerance.
