not degrees Kelvin
You do not write °K at any time.[1] --Mtur 16:31, 30 March 2007 (EDT) Further reading
In 1954, the definition of the Celsius scale itself was changed. Rather than using the freezing and boiling points of water at 1 atmosphere of pressure, the degree interval Celsius was set equal to the degree interval Kelvin, and 0 °C was set equal to 273.15 degree Kelvin. Thus, the Kelvin scale became the fundamental temperature scale. Its fundamental unit was the degree Kelvin, with the symbol °K. Unfortunately, here also the word degree introduced complications as temperature measurements became finer. For example, the metric system dictates that 0.01 meter is equal to 1 centimeter. However, is 0.01 degree Kelvin equal to 1 centidegree Kelvin, or 1 degree centiKelvin? In order to remove this ambiguity, scientists agreed in 1967 that degree Kelvin would no longer be used to describe the fundamental temperature interval. The fundamental temperature interval would be called simply kelvin (with a lowercase k), and the symbol would be K without any degree symbol (°). The temperature interval in the Celsius scale, however, would retain the word degree, the capitalized C in Celsius, and the symbol °C.[2]
