Celsius

Celsius is the scale of measure for temperature.

• It is also called the Centigrade scale (centigrade means divided into 100).
• It is a standard Imperial metric.

Description (Specifications)

The Celsius scale is a system for measuring temperature. It is divided into degrees (symbol º) and is based around the freezing and boiling points of water (H₂O).

• The standard abbreviation is C.

0ºC is the point at which water freezes (transforms from a liquid into a solid: ice) within an atmospheric pressure of 1 atm.

100ºC is the point at which water boils (transforms from a liquid into a gas: steam or water vapor) within an atmospheric pressure of 1 atm.

The lowest temperature that is theoretically possible is -273.15ºC (absolute zero). At this temperature, the motion of particles which constitute heat is minimal.

History & Background (Dossier)

The Celsius scale was defined as a means of defining temperature on Terra prior to the foundation of the Terran Confederation: it is named for Anders Celsius, a Terran astronomer born around -2803. Technologists found the Celsius scale useful as the concept of the Technology Level and standardized ideas about sophont society development began to take form.
