The torr (symbol: Torr) is a non-SI unit of pressure with the ratio of 760 to 1 standard atmosphere, chosen to be roughly equal to the fluid pressure exerted by a millimeter of mercury, i.e., a pressure of 1 Torr is approximately equal to one millimeter of mercury.
Pressure from the weight of a U.S. quarter lying flat: 133 Pa: 1 torr â 1 mmHg Â±200 Pa ~140 dB: Threshold of pain pressure level for sound. Prolonged exposure may lead to hearing loss.
