torr
- Definition: The torr is a unit of pressure based on the millimeter of mercury (mmHg). It is defined as 1/760 of standard atmospheric pressure.
- Symbol: The symbol for torr is “Torr”.
- Usage: Torr is commonly used in various fields such as meteorology, engineering, and physics to measure pressure.
millimeter of mercury
- Definition: The millimeter of mercury (mmHg) is a unit of pressure that represents the pressure exerted by a column of mercury one millimeter high.
- Symbol: The symbol for millimeter of mercury is “mmHg”.
- Usage: mmHg is widely used in medicine, particularly in measuring blood pressure, and in various scientific applications.
Origin of the torr
- The torr was named after the Italian physicist Evangelista Torricelli, who is credited with inventing the barometer in the 17th century. The unit was established to provide a practical measurement for pressure.
Origin of the millimeter of mercury
- The millimeter of mercury originates from the use of mercury in barometers and manometers. This unit reflects the height of mercury that corresponds to a given pressure, making it a vital measurement in both scientific and medical fields.
