Explanation

Formula: Pounds per Square Inch = Kilopascals × 0.145038. Why: this is a cross-system pressure conversion. The calculator normalizes the value through pascals, then applies the exact target-unit constant for consistent engineering and reference use.

Kilopascals (kPa): a pressure unit equal to 1,000 pascals, widely used in engineering, weather, and industrial specifications.

Pounds per square inch (psi): an imperial pressure unit widely used in tires, hydraulics, compressed gas systems, and general mechanical work.

This route is useful when translating pressure values across SI, metric engineering, and imperial conventions so datasheets, gauges, and calculations stay comparable.

This conversion is purely multiplicative because both units reduce through pascals using fixed pressure constants with no offset.
