Celsius scale

Physics
  • A temperature scale in which the fixed points are the temperatures at standard pressure of ice in equilibrium with water (0°C) and water in equilibrium with steam (100°C). The scale, between these two temperatures, is divided in 100 degrees. The degree Celsius (°C) is equal in magnitude to the kelvin. This scale was formerly known as the centigrade scale; the name was officially changed in 1948 to avoid confusion with a hundredth part of a grade. It is named after the Swedish astronomer Anders Celsius (1701–44), who devised the inverted form of this scale (ice point 100°, steam point 0°) in 1742.

Chemical Engineering
  • A temperature scale devised in 1742 by Swedish astronomer Anders Celsius (1701–44). Celsius used the reference points of the freezing point of water (0ºC) and boiling point of water (100ºC) divided equally by 100 degrees. The Celsius scale officially replaced the earlier centigrade scale in 1948. The conversion from degrees Fahrenheit is:

    °C=59(°F32)

    Degrees Celsius has the same magnitude as the kelvin. Note that 0ºC is equal to 273.15K.
