The units on the Kelvin scale are simply called 'kelvin' because it is not relative to any reference point.
Yes, the degree symbol is used with the Kelvin scale. For example, the temperature 0 degrees Kelvin is written as "0 K."
Because when expressing absolute temperature using the Kelvin scale, the unit of temperature is not the "degree", it's the "Kelvin". The "Kelvin" is a unit of temperature equal to one Celsius degree. There's no such thing as a "Kelvin degree".
The symbols for each temperature scale are simply the first letter of each scale, so for degrees Kelvin the symbol is K, for degrees Celcius (or Centigrade) the symbol is C, and for degrees Fahrenheit the symbol is F.
The temperature scale where water froze at 273 degrees is likely the Kelvin scale. On the Kelvin scale, 0 degrees represents absolute zero, the lowest possible temperature where all molecular motion ceases. Hence, 273 degrees Kelvin corresponds to 0 degrees Celsius.
The SI system uses the Kelvin temperature scale, which begins at 0° (at absolute zero) and uses the same degree size as the Celsius or centigrade scale. Water freezes at 273.15 °K, which is the equivalent of 0° Celsius. There are no negative temperatures on the Kelvin scale, as it is based on absolute zero and no lower temperature state can exist.
The Kelvin temperature scale
The kelvin (symbol: K) is a unit increment of temperature and is one of the seven SI base units. The Kelvin scale is a thermodynamic (absolute) temperature scale referenced to absolute zero, the absence of all thermal energy. So by definition, the temperature of a substance at absolute zero is zero kelvin (0 K). The secondary reference point on the Kelvin scale is the triple point of water (0.01 degrees Celsius). The Kelvin scale is the difference between these two reference points, with the kelvin defined as one 273.16th of this scale. The Kelvin scale and the kelvin are named after the Belfast-born physicist and engineer William Thomson, 1st Baron Kelvin (1824-1907), who wrote of the need for an "absolute thermometric scale". Unlike the degree Fahrenheit and degree Celsius, the kelvin is not referred to as a "degree", nor is it typeset with a degree symbol; that is, it is written K and not °K. The kelvin and the degree Celsius are often used together, as they have the same interval, and 0 kelvin is −273.15 degrees Celsius.short answer - temperature.Kelvin is the absolute temperature scale, with the same size degree as Celsius, but with zero set at 'absolute zero' - the temperature you can't go lower than...
The Kelvin scale is an absolute temperature scale where 0K represents absolute zero. The absolute temperature scale refers to any temperature scale that starts at absolute zero, such as the Kelvin scale. So, the Kelvin scale is a specific type of absolute temperature scale.
Degrees in Kelvin scale = Degrees in Celsius scale + 273,15.
183 celsius in Kelvin = 183 + 273.15= 456.15 Kelvin
