This calculator allows you to convert pressure values from pounds per square inch (psi) to Torr (mmHg).
Definition: Pound-force per Square Inch (psi)
A pound-force per square inch (symbol: psi) is a unit of pressure used in the imperial and US customary systems. It represents the pressure resulting from a force of one pound-force applied over an area of one square inch.
Definition: Torr (mmHg)
A Torr (symbol: Torr), also known as millimeter of mercury (mmHg), is a unit of pressure named after Evangelista Torricelli. It is defined as the pressure exerted by a 1 mm high column of mercury at 0°C under standard gravity. It is commonly used in vacuum measurements and low-pressure applications.
Formula for Psi to Torr Conversion:
Pressure in Torr=Pressure in psi × 51.7149
How to Convert Psi to Torr: Example Calculation
Suppose you have a pressure of 14.696 psi (which is equivalent to atmospheric pressure at sea level).
To convert it to Torr:
14.696×51.7149=760 Torr
So, 14.696 psi is equal to 760 Torr.
