What is the difference between pounds per square inch and pascals?

Pounds per square inch (psi) and pascals (Pa) are both units of pressure, but they belong to different measurement systems. Psi is part of the imperial system, commonly used in the United States, while pascals are part of the metric system, widely used internationally. One psi is equivalent to approximately 6,894.76 pascals, indicating that pascals represent a smaller unit of pressure compared to psi.
