    Twice as cold should be half the heat energy. So it should be the half way point between 0 Centigrade and absolute zero. As endeavour said "273/2 = 136.5 K". Although i think it's 136.6 K, because 0 C is 273.16 K (sorry)

    The nature of centigrade is based on freezing and boiling point of water - it was correct to convert to fahrenheit, because what can you do with 0c? The answer is nothing, but it represents 32F, so twice as cold is 16F, and if you convert that to centigrade you get -8.8888 c. Easy.
    Exactly, it's only relative to b.p. of water. 0 kevlin is the lowest temperature (when all molecules stop moving), so it makes more sense to standardise it from that.

    If you were calculating the kinetic energy of molecules at a temperature, you use E=3/2nRT where T is in Kelvin.

    True. It's only the absence of warmth

    Look mate, keep it simple, just convert between Celcius and Fahrenheit. Absolute zero being the coldest something can be, so that all atoms stop? And you're saying that twice as cold as it is in december is halfway to absolute zero? Nah, I'm not having that. If you look at the logic, I don't see why converting fahrenheit and celcius is wrong, seems natural to me.

    THink about it 0c is cold, and -8.888 would be about twice as cold, and that's very cold (think about it, it is rarely ever -8 here, for a good reason). I know, I'm now not calculating, but where the logic and superificial evidence is there, I can't disagree with myself.

    Well, yeah. Twice as cold means half the heat. If u take away half the heat, you get half way to absolute zero. That seems natural to me

    Converting to farenheit and then back to celcius just lacks logic.

    What if it was a 4 times as cold? Would the temperature then be -13.33 celcius?
    So you've gone from 0 C, -8.89 C to -13.33 C. That's just meaningless.

    It certainly was and if i'm wrong, which it now appears I am, then i'l hold my hands up. Maths and the sciences never quite agreed with me, Kelvin who? lol

    "twice as cold".

    hmm. that would tend to suggest "cold" is a single and uniform thing. it is not.

    I know nobody said I was, but I just thought i'd point it out, nor am I a scientist nor a mathematician.
