Formula

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

Examples

For instance, 1 inHg is strictly defined as roughly 25.400084007140606 Torr. If you are dealing with a larger scale, such as 50 inHg, the resulting Torr value maintains this exact linear proportionality.

Reverse Formula

The inverse conversion (Torr back to Inch 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 inHg to Torr calculations is the misapplication of unit prefixes (like centi- or milli-). Additionally, confusing Inch of mercury with similar units in different systems (like US vs. Imperial) can lead to significant discrepancies.
