Torr to inHg

torr

• Definition: The torr is a unit of pressure defined as 1/760 of an atmosphere. It is commonly used in various scientific and engineering applications.

• Symbol: The symbol for torr is “Torr”.

• Usage: Torr is often used in vacuum measurements, meteorology, and various scientific contexts where precise pressure readings are necessary.

inch of mercury

• Definition: An inch of mercury (inHg) is a unit of pressure that represents the pressure exerted by a column of mercury one inch high. It is commonly used in weather forecasts and barometers.

• Symbol: The symbol for inch of mercury is “inHg”.

• Usage: Inch of mercury is frequently used in meteorology, aviation, and various engineering applications to measure atmospheric pressure.

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. His work laid the foundation for understanding atmospheric pressure, leading to the establishment of this unit.

Origin of the inch of mercury

• The inch of mercury derives its name from the physical properties of mercury, a dense liquid metal. Historically, it was used in barometers to measure atmospheric pressure, with the height of the mercury column being a direct indication of that pressure.
