Pa to Torr

pascal

• Definition: The pascal (Pa) is the SI unit of pressure, defined as one newton per square meter.

• Symbol: The symbol for pascal is “Pa”.

• Usage: Pascals are commonly used in various scientific and engineering applications to measure pressure, stress, and tension.

torr

• Definition: The torr is a unit of pressure defined as 1/760 of an atmosphere, which is approximately equal to the pressure exerted by a column of mercury 1 millimeter high.

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

• Usage: Torr is often used in vacuum measurements and in fields such as meteorology and physics.

Origin of the pascal

• The pascal is named after Blaise Pascal, a French mathematician, physicist, and inventor who made significant contributions to the understanding of fluid mechanics and pressure.

Origin of the torr

• The torr is named after Evangelista Torricelli, an Italian physicist and mathematician who invented the barometer and made foundational contributions to the study of atmospheric pressure.
