===About Degrees Celsius===
: '''Degrees Celsius''' is shortened to '''°C''' with the degree symbol ° followed by an upper case C.
: '''Degrees CelciusCelsius''' are 273° away from the [[SI Unit|SI unit]] for [[temperature]]; the [[Kelvin]];
:*0'''°C''' = 273 [[Kelvin]]
:*-273'''°C''' = 0 [[Kelvin]] ([[Absolute Zero]] the coldest [[temperature]] possible in the [[Universe]]).
: A change of 1'''°C''' is the same as change of 1 [[Kelvin]].
: A '''degree Celsius''' is 100th of the [[temperature]] change between the [[Melting Point|melting point]] and [[Boiling Point]]|boiling point]] of [[water]] at normal [[Atmospheric Pressure|atmospheric pressure]].

===Meaning===
'''Degrees Celsius''' are a [[unit]] of temperature in the [[Degrees Celsius|Celsius scale]] where 0°C is the [[temperature]] at which [[water]] [[Freezing|freezes]] and 100°C is the [[temperature]] at which [[water]] [[boil]]s at [[Standard Atmospheric Pressure|standard atmospheric pressure]].
===About the Celsius Scale===
*Defined in terms of the [[Triple Point|triple point]] of [[water]], where the [[temperature]] is exactly 0.01'''°C'''.
*Used worldwide for most [[temperature]] [[measure]]ments except in scientific research where the [[Absolute Temperature|Kelvin scale]] is preferred.
*Named after the Swedish astronomer Anders Celsius.
*Commonly used in everyday [[temperature]] [[measure]]ments and weather reporting.
*The '''Celsius''' scale is part of the [[Metric System|metric system]].
*The interval between the [[freezing]] and [[boiling]] points of [[water]] is divided into 100 '''degrees'''.
*The '''Celsius''' scale is also used in various scientific and engineering contexts.
===Examples===
*Weather forecasts report temperatures in degrees '''Celsius'''.
*Laboratory measurements often use the '''Celsius''' scale for [[temperature]] readings.
