< /ˈɑn dərs/, 1701–44, Swedish astronomer who devised the Celsius temperature scale.
- 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
- Thermodynamics. of or relating 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: CCompare Kelvin(def 3).
- denoting a measurement on the Celsius scaleSymbol: C
1850, for Swedish astronomer Anders Celsius (1701-1744) inventor of the centigrade scale in 1742.
- 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.
- Relating to a temperature scale on which the freezing point of water is 0° and the boiling point of water is 100° under normal atmospheric pressure. See Note at centigrade.
- Swedish astronomer who invented the centigrade thermometer in 1742.
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 (see also Fahrenheit).)
