Torr to GPa

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: The torr is commonly used in various fields, including meteorology and vacuum technology, as a measure of pressure.

gigapascal

• Definition: The gigapascal (GPa) is a unit of pressure equal to one billion pascals. It is commonly used in materials science and engineering to express high pressure.

• Symbol: The symbol for gigapascal is “GPa”.

• Usage: Gigapascals are often utilized in contexts such as the measurement of material strength and the performance of industrial processes.

Origin of the torr

• The torr is named after the Italian physicist Evangelista Torricelli, who invented the barometer in the 17th century. The unit was established to provide a measure of pressure related to the height of a mercury column, reflecting the principles of fluid mechanics.

Origin of the gigapascal

• The gigapascal is derived from the pascal, which is named after Blaise Pascal, a French mathematician and physicist. The pascal is the SI unit of pressure, and the gigapascal is simply a larger scale used to represent high pressures, particularly in industrial and scientific applications.
