As far as C vs F vs K is concerned
F is part of a completely arbitrary system. Consisting of Fixed values amongst the Whole of the measuring system, that being the Imperial System. This requires the Memorization of not only Values, but even Mathematic Formulas for Conversion between different measures within a certain type of Measurement: For eg: inches/ft/yards/Miles are all Arbitrary amounts within Distance; Ounces/Pints/Quarts/Gallons are all Arbitrary amounts within Volume.
C is part of a Mathematical system. All Fixed Values are derived through Mathematics and not some long dead persons dimensions(like much of the measurements used in the Imperial system). Not only are the Fixed Values Mathematically defined, but all the various ways of stating a Measurement are Mathematically related. For eg: mm/cm/dm/M/KM are all easily derived through simple Mathematics, 1000mm=100cm=10dm=1M=0.0001KM.
Not only are C measurements Mathematical within a particular measurement type(Volume, Distance, Temperature), but there are extensive Mathematical relationships between the measurement types. This allows for Verification of the various Measures, thus giving the Metric system a high degree of Accuracy and a strong Scientific basis.
K is also a Mathematical system. Fixed Values are based on Absolutes, which makes it the most accurate of any system. This is very useful for Science and particularly for certain fields of Science that require measurements close to the Absolute.
It's not so good for Day-to-day common usage though. Mainly because it lacks the intuitiveness of F or C. For eg: 0C/32F=273K, 50C/122F=323K, both C/F give values that make more sense to People and their everyday lives, simply because 0C or near 0F denotes a point of significant change. 0C approaches a Danger point as does 50C.
If everyone used and were taught K, I suppose "Intuitiveness" wouldn't matter so much, but it would seem to be as Arbitrary a Temp Measuring system for Day-to-Day Life as F. Add in that Conversions from C to K is relatively simple and you have little reason to replace C with K.
***Not a Mathematician, Rocket Scientist, College Grad, recent High School Grad, nor did I stay at a Holiday Inn last night. Just from what I remember and/or have picked up over the years. I'm sure some of it is wrong or not entirely accurate, but it's basically correctish.***
They're all Arbitrary. Will you Understand that with Random Capitals tossed in to Help you?
