I've thought about this and got myself very confused! - 0 degrees Celcius is 32 degrees Farenheit so you could argue that twice as cold is half as warm which would be 16 Farenheit (minus 9 Celcius).
But it gets worse - 10 degrees C = 50 F
20 degrees C = 68 F
So doubling a temperature is all dependent on which scale you are using

I think everyone is missing something who says 0 is cold or warm for that matter. You can switch scales so there is a number to multiply, but what you should ask is what is the average temperature in the area you're comparing. If the average daily temp. is 7 (I'll use metric) and it's 0 then to be twice as cold would be -7 if the average temp. is below 0 then really it's not cold.

Twice as cold is half as warm. Heat or the absence of heat is measured in calories, BRUs, or joules. Temperature is an imperfect measure of heat content. One can add more heat to boiling water, for example, and the water will boil faster, but its temperature will stay at 100 deg C. (at normal standard atm pressure).
Heat is a form of energy called thermal energy. It is a measure of the vibration of the molecules of the body that contains the heat. As heat is added, the molecules vibrate more; less heat and they vibrate less. At the temperature called absolute zero all molecular vibration would cease, but, thus far, we have not reached that level experimentally.
So the answer is, if its twice as cold today, there is half the heat there was yesterday.

Arguably you should be using absolute zero as the basis of your calculations. Absolute zero is -273 C therefore 0 C is 273 c above Absolute Zero.
Twice as cold would be half as hot ie 273/2 = 136.5 Absolute or -136.5C - that would certainly freeze the watsits off a brass monkey.

Since absolute zero, which is the coldest possible temperature, is minus 273 Celsius, then twice as cold would be -136 Celsius.

I think our perception of twice as cold is relative to the difference between our body temperature and the actual temperature. Using a normal body temp of 35 degrees, twice as cold relative to how we feel the cold would be -35 deg c.

I think that when people say twice as cold they do not mean it literally like your question suggests. However, if you thought of cold as how far below optimal temperature it was, lets say optimal temperature was 70 degrees, then you could simply double that difference.

Twice as cold

Too cold to go outside.

you need a reference to what it is twice as cols AS ....
you can't double the lack of any reference....
you play on the fact that twice zero is still zero... we're not multiplying degrees....but the difference between temps for yesterday...today...and tomorrow
