What is millimeter mercury (0°C)?

Millimeter mercury (0°C), abbreviated as mmHg, is a pressure unit corresponding to the pressure exerted by a 1 mm column of mercury at 0°C under standard gravity.

Where is psi commonly used?

Psi, or pound per square inch, is used in Imperial/US customary systems, widely applied in automotive tire pressure, hydraulic systems, compressed gas cylinders, and water pressure measurement.

How precise is the conversion from mmHg to psi?

The conversion uses a fixed rate, but precision can vary depending on measurement calibrations and exact physical conditions like mercury temperature and gravity.
