[sel-see-uh
s, -shee-] 
| 1. | An⋅ders [ahn-ders] , 1701–44, Swedish astronomer who devised the Celsius temperature scale. |
| 2. | Also, Centigrade. pertaining to or noting a temperature scale (Celsius scale) in which 0° represents the ice point and 100° the steam point. Symbol: C |
| 3. | Thermodynamics. of or pertaining to a temperature scale having the same units as the Celsius scale but in which the zero point has been shifted so that the triple point of water has the exact value 0.01°; Celsius temperatures are computed from Kelvin values by subtracting 273.15 from the latter. Symbol: C Compare Kelvin (def. 3). |
| Cel·si·us (sěl'sē-əs, -shəs) adj. Abbr. C Of or relating to a temperature scale that registers the freezing point of water as 0° and the boiling point as 100° under normal atmospheric pressure. See Table at measurement. [After Anders Celsius.] |
| Celsius, Anders 1701-1744. Swedish astronomer who devised (1742) the centigrade thermometer. |
A temperature scale, also called centigrade, according to which water freezes at zero degrees and boils at one hundred degrees.
A temperature scale in which zero degrees is the freezing point of water and 100 degrees is the boiling point. Temperature in this scale is generally denoted by °C or, in scientific usage, C alone. (Compare Fahrenheit.)
