## About torr

The **torr** is a non-SI unit of pressure equal to 133.3224 pascals (1 Torr = 133.3224 Pa), the SI derived unit of pressure.

The torr (Torr) is also equal to 1.333224 hectopascals (hPa), or 0.1333224 kilopascals (kPa), or about 0.00131578947 atmospheres (atm), or 0.00133322368 bars (bar), or 1.0 millimeter of mercury at 0 °C (mmHg), or 0.53524 inches of water at 4 °C (inH_{2}O), or 0.0193368 pounds per square inch (psi) or 2.78449556 pounds per square foot (psf).

The torr unit is named after the Italian physicist and mathematician Evangelista Torricelli who lived between 1608 and 1647. The torr is used in engineering and physics.
