Formula

To execute this calculation, the value in Millimeter of mercury is first normalized to the base Pressure unit (Pascal) before being scaled to Pound/square inch. The direct multiplier for Millimeter of mercury to Pound/square inch is determined by the ratio of their scientific definitions.

Examples

For instance, 1 mmHg is strictly defined as roughly 0.0193367136782136 psi. If you are dealing with a larger scale, such as 50 mmHg, the resulting psi value maintains this exact linear proportionality.

Reverse Formula

The inverse conversion (Pound/square inch back to Millimeter of mercury) is equally valid and uses the reciprocal of the primary ratio. Our interface allows you to toggle this direction instantly to verify both sides of the Pressure equation.

Common Mistakes

The most frequent error in mmHg to psi calculations is the misapplication of unit prefixes (like centi- or milli-). Additionally, confusing Millimeter of mercury with similar units in different systems (like US vs. Imperial) can lead to significant discrepancies.
