Megapascals (MPa)
Definition
A megapascal (MPa) is a unit of pressure equal to 1,000,000 pascals or 1,000 kilopascals. It is used for expressing very high pressures.
History
The megapascal became the standard unit for material science and structural engineering as SI units spread globally. It replaced older units like kgf/cm² in many engineering specifications.
Current use
Megapascals are the standard unit for expressing tensile strength, yield strength, and compressive strength of materials. Concrete, steel, and composite material specifications use MPa worldwide.
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.
