Pascals (Pa)
Definition
A pascal (Pa) is the SI unit of pressure, defined as one newton per square meter (1 Pa = 1 N/m²). It measures the force applied perpendicular to a surface per unit area.
History
The pascal was named after Blaise Pascal, the French mathematician and physicist who made pioneering contributions to fluid mechanics and pressure studies in the 17th century. It was adopted as the SI unit of pressure in 1971.
Current use
Pascals are the standard pressure unit in science and engineering worldwide. Atmospheric pressure, material stress, and sound pressure levels are all measured in pascals or their multiples.
Torr
Definition
A torr is a unit of pressure equal to 1/760 of a standard atmosphere, or approximately 133.322 pascals. It is nearly equivalent to one millimeter of mercury (mmHg).
History
The torr was named after Evangelista Torricelli, the Italian physicist who invented the mercury barometer in 1644. It was defined to provide a convenient way to express vacuum and low-pressure measurements.
Current use
Torr is widely used in vacuum science, semiconductor manufacturing, and laboratory settings for measuring low pressures. It remains a standard unit in physics and materials processing.
