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.
Kilopascals (kPa)
Definition
A kilopascal (kPa) is a unit of pressure equal to 1,000 pascals. It provides a practical scale for many common pressure measurements.
History
The kilopascal became widely used with the adoption of SI units in the 20th century. It offered a convenient alternative to the bar and atmosphere for expressing everyday pressures.
Current use
Kilopascals are commonly used for tire pressure specifications (outside the US), blood pressure in some countries, weather station atmospheric pressure reports, and industrial process pressures.
