The standard atmosphere was originally defined as the pressure exerted by 760 mm of mercury at 0 °C (32 °F) and standard gravity (gn = 9.80665 m/s ). It was used as a reference condition for physical and chemical properties, and was implicit in the definition of the Celsius temperature scale, which defined 100 °C (212 °F) as the boiling point of water at this pressure. In 1954, the 10th General Conference on Weights and Measures (CGPM) adopted standard atmosphere for g… WebbDescription The atmosphere is the space around the Earth which is filled by a mixture of gasses held against the Earth by the force of gravity. This mixture of gasses we call air.

Prior to the redefinition of the unit, one torr was equal to one mm Hg. While this is close to 1/760 of the standard atmospheric pressure, the two definitions differed by about 0.000015%. tracing p\u0026id
