You pose a very interesting question. What is the temperature if it's
twice as cold as zero degrees? The Fahrenheit and Celsius temperature
scales are "relative" temperature scales, in that they are both
relative to a couple of specific temperatures, namely the freezing and
boiling points of water.
Let's make your question a little more specific: "What is the
temperature if it's twice as warm as 0 degrees Celsius (the freezing
point of water)?" To answer this question we need to convert this
Celsius temperature to an "absolute" temperature scale, a scale with
no negative temperatures. We'll use the Kelvin scale.
0 degrees Kelvin is the point at which all motion in matter stops; it
is known as "absolute zero." No temperature can exist that is lower
than 0 degrees Kelvin. The formula to convert from Celsius to Kelvin
temperature is K = C + 273.15, where K is the Kelvin temperature and C
is the Celsius temperature. So 0 degrees Celsius is equal to 273.15
degrees Kelvin. We can double this number to get 546.30, the
temperature that is twice as warm as 0 degrees Celsius. We can then
subtract 273.15 from our answer to convert it back to the Celsius
scale.
The temperature is 273.15 degrees Celsius when it is twice as warm as
0 degrees Celsius.
Makes perfect sense, doesn't it? Thanks for writing, and write back
any time.

Despite all the extravegant math,
The answer must remain 0 degrees celcius, as the unit referred to in the question is celcius, the answer will be delivered in celcius.
But still an interesting question and part of me believes all kelvin type answers to be true also.

Well I think the lowest temperature is -273. So double 0. would be 273 degrees.
Its not like in maths where 2 x 0 equals zero

Depends on your point of reference. 0 degrees Celcius is 273 degrees Kelven or 32 degrees F. But in any case, it is the freezing point of water. If that is your reference, then if you double 0, from the freezing point of water, you still get 0.

O degrees celcius is 273 degrees above absolute zero.
273 times two, equals 556 degrees above absolute zero and 273 degrees celcius.

When you double zero you get zero; but when you double the temperature (represented by zero degrees celsius) you get twice the temperature on an absolute scale. Was this a clever trick question? My guess is that you knew the answer, right? Your icon looks alert, cunning and sly.

wow, a lot of answers with kelvin and such.
Start with the math part.
to double means to multiply times 2
so (0x2)= 0
so 0 degrees C = 0 degrees C.
(followed up and read some answers. Makes math interesting when you look at stuff like 0C to be equiv to other valid answers. In that case you could be 64F, 546K or 0C...heck maybe even other crazy answers. Cold as a titty in a brass bra?)

It's still 32 degrees F
