The Standard Atmosphere is a unit of pressure.

Description (Specifications)[edit]

The descriptions of Atmospheres are given in the relative terms of Standard Atmospheres, rather than the absolute units, as a method of making comparisons to the human physiological norm easier.

One Atmosphere is defined as being precisely equal to 101.325 kPa (kilopascals). The pascal is a unit of force used to quantify pressure and is defined as one newton per square meter.

  • The Atmosphere is based on the mean surface atmospheric pressure of Terra.
  • The standard abbreviation is atm.

Atmosphere Types[edit]

Within Charted Space, the atmospheres of worlds are rated according to a standard scale, based on their mean surface pressure.

History & Background (Dossier)[edit]

The Atmosphere was first defined as a unit of pressure on Terra prior to the foundation of the Terran Confederation. It is defined as the mean surface pressure of Terra's atmosphere. The true atmospheric pressure of a world can vary, even on Terra: the local atmospheric pressure can vary from the standard by as much as 15%, affected by weather, temperature, tides, and altitude. Technologists found the Atmosphere useful as the concept of the Technology Level and standardized ideas about sophont society development began to take form.[1]
