About pound per square inch
The pound per square inch (or pound-force per square inch) is a unit of pressure equal to 6,894.757 pascals (1 psi = 6,894.757 Pa), the SI derived unit of pressure.
The pound per square inch (psi) is also equal to 68.9475729 hectopascals (hPa), or 6.894757 kilopascals (kPa), or about 0.0680459 atmospheres (atm), or 0.0689475 bars (bar), or 51.7149 millimeters of mercury at 0 °C (mmHg), or 27.6799 inches of water at 4 °C (inH2O), or 144 pounds per square foot (psf) or 51.7149 torr (Torr).
The pound per square inch is the pressure that results when a force of one pound-force is applied (uniformly and perpendicularly) on a surface of one square inch. The pound-force (lbf) is a unit of force while the square inch (sq in) is a unit of area.
The pound per square inch (psi) is commonly used in the United States as a unit of pressure.
