Explanation

Formula: Pounds per Square Inch = Millimeters of Mercury × 0.019337. Why: both units are pressure scales with fixed pascal equivalents, so the conversion moves through pascals and preserves a single deterministic factor.

Millimeters of mercury (mmHg): a pressure unit tied to a fixed pascal equivalent and commonly used in medical, laboratory, and vacuum-related readings.

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 readings between psi and mmHg in mechanical, vacuum, laboratory, and instrumentation contexts.

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