Atmospheres (atm)
Definition
A standard atmosphere (atm) is a unit of pressure defined as exactly 101,325 pascals. It represents the average atmospheric pressure at sea level.
History
The standard atmosphere was defined in 1954 as a reference standard for pressure. It was historically based on mercury barometer readings and the average weight of the Earth's atmosphere at sea level.
Current use
Atmospheres are used in chemistry (standard conditions for gas calculations), diving (dive depth pressure ratings), and as a reference point for comparing relative pressures across different systems.
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.
