Temperature

If the forecaster says tomorrow will be twice as cold as today, and today it reached minus 1c I assume tomorrow it will be -2c.
But what if today it reached 0c? What will be the reading tomorrow?

do not try and attach meaning to what is a figure of speech. We use them all the time. what is "cold" for a start I mean it's 273K anyway and that is positivley tropical in universal terms so cold means negative hot so ................. get out more!
Some one said the other day " I turned around and said...." well obviously you had your back the them to start with and that's rude! see what I mean, no rhymme or reason just drivel.

Comparives such as 'twice a much as' or 'half as much as' depend on there being a proper measurement scale where zero is definitely zero.
With measures such as mass or distance there is a clear value for zero. For temperature, however, the centigrade scale is an artificial scale where zero was set at the temperature at which water freezes and 100 is the temperature at which water boils.
For temperature the true scale is degrees Kelvin where 0 degrees K is said to be absolute zero. On this scale 0 degrees C is 273 degrees Kelvin.
So absolute zero is -273 degrees C.
So, assuming 0 degrees K or -273 degrees C is definitely the lowest the temperature can possible be, I suggest we can argue that if it was 0 degrees C today then next day it fell to half that temperature it would fall to -136.5 degrees C.
I'm not a scientist but i remember this from school. But I'm happy to be corrected by science specialists.

I hope we have established that 0�C is not twice as cold as 0�C!
Another wrong answer no-one has given is to say that twice as cold as 0�C is -9�C. The argument is that 0�C on the Fahrenheit scale equates to 32�F. So twice as cold would be 16�F. This converts to 9�C.
Nonsense of course- it just confirms that temperature in degrees f or C is measured on arbitary scales (in that there is no true zero), unless we use the Kelvin scale and accept that absolute zero is -273�C

At last, a question I can sink my teeth into.
The reason we expose fallacies is so that we do not have to live with and endure their consequences, suffering in silence their parasitic existence as with a festering sore on our backside. So let's put this one to rest, shall we?
To begin with we should cast aside the misleading and blatantly absurd assumption that -2c is irrevocably twice as cold as -1c. What any of this has to do with the velocity of light is a topic that can only be discussed meaningfully by those well versed in the nuances of relativity theory.
In light of most of the discussion that has taken place so far in this thread (taking my own in particular into consideration) it should be blatantly clear to all but the most hardened skeptic that bringing this question to a meaningful resolution within this forum is about as likely as getting a reliable forecast for tomorrow's weather . . . imho!
Nevertheless, those who have lent their keen insight into the problems inherent in the question framed by this thread should not go without some recognition in the form of worthy praise and so to them I resound with a hearty, "Here here!"

I quite liked your answer mib - but WHY is it absurd to assume that -2's double that of -1???? I'm sure what you say's correct, but could you explain in simple language for me? If the temperature was -1 today, and tomorrow's temperature was expected to be double that....I would've been tempted to expect it to reach -2 then.
