We assume you are converting between **pound/square inch** and **millimeter of mercury [0 °C]**.

You can view more details on each measurement unit:

psi or
mmHg

The SI derived unit for **pressure** is the pascal.

1 pascal is equal to 0.00014503773800722 psi, or 0.0075006156130264 mmHg.

Note that rounding errors may occur, so always check the results.

The pound per square inch or, more accurately, pound-force per square inch (symbol: psi or lbf/inē or lbf/inē) is a unit of pressure or of stress based on avoirdupois units. It is the pressure resulting from a force of one pound-force applied to an area of one square inch.

The torr (symbol: Torr) or millimetre of mercury (mmHg) is a non-SI unit of pressure. It is the atmospheric pressure that supports a column of mercury 1 millimetre high. The unit is named after Evangelista Torricelli, Italian physicist and mathematician, for his discovery of the principle of the barometer in 1643.
