Pound per square inch to torr (psi to mmHg) pressure conversion table shows the most common values for the quick reference. Alternatively, you may use the converter to convert any other values.
1 Psi = 51.7149326 Torr
Psi is defined as 1 pound of force applied per square inch. It is the main pressure unit in United States and widely used in all kinds of applications. 1 pound per square inch (psi) equals to 6 894.75729 pascals.
Torr is 1/760 of an atm (atmospheric pressure). mmHg (millimeter of mercury) is a pressure of fluid from one millimeter of mercury. Torr and mmHg are different pressure units but the difference is very low (about 0.000015%) and they are treated as the same pressure unit in most applications. It is used in physics and engineering and mmHg is commonly used in measuring the blood pressure.
