>>>You show "degrees Kelvin" as a unit (as one of your "standard" units and in a table below incongruously under the column head "Metric Heat Unit"). For quite some time now it has been only "kelvin"; the "degree" portion was dropped. Thus the triple-point of water occurs at 273.16 kelvins (273.16 K). >>>
I have to confess to being guilty of that one, as someone who did his dissertation in low-temperature physics many moons ago when "degrees Kelvin" was the norm. Just curious, what's the reason for emphasizing "kelvins" over "degrees Kelvin? It seems the latter more easily facilitates the conversion back and forth between Celsius and Kelvin. Nat
