What does pound-force per square inch measure?

Pound-force per square inch (psi) measures pressure as one pound-force applied to an area of one square inch, commonly used in imperial contexts.

Why convert psi to megapascal [MPa]?

Converting psi to MPa helps express pressure in widely accepted metric and scientific units, especially useful in engineering and research.

Is this conversion suitable for hydraulic system pressures?

Yes, converting psi to MPa is common for specifying operating and test pressures in hydraulic and pneumatic systems.
