I'm going to post this one here instead of the trivia thread since i'am not 100% sure of the answer.!

If it's 0 degree Farenheit outside, and the forecast for tomorrow is "it will be twice as cold" what will be the temperature in Farenheit?

I believe it would be -229.835 degrees F, but with a windchill factor - - who knows!!

There isn't really any such thing as cold is there? Just a lack of heat so it would more accurately stated as "half as hot". I know - picky picky. Pick your interpretation. -229F as mentioned or 32 below freezing times 2 = -64F or 0 times 2 = 0F

My personnal pick would be -229 f.You transform 0 farenheit in kelvin degrees , which is about +458k.and divide by 2,and put it back in farenheit!

Just thought i'd offer an explanation as to why people are chosing about -230 degrees F to anyone left in the dark. Absolute zero is the temperature at which all motions stops. On the F scale, this is about -460 F. So looking at it as twice as cold being the same as half as hot, and taking temperature as a linear measure of heat, the answer is about -230 F.

The ideal temperature is approximately 72^oF. Disregarding drafts and humidity, anything hotter is described as being on the warm side and anything colder is described on the cool side.

Using 72^oF as the measuring stick, an ambient temperature twice as cold as 0^oF would be -72^oF.

I like coldfuse's answer better, if you are talking in reference to a person and not to an inanimate object, or for that matter an animate object with a diff. comfortable temp. it adds a lot of uncertainty to the definition though. Different people are comfortable at different temps based on sex, body fat, what type of climate they were brought up in, and probably a few other things. An then of course you need to considerr whether this is a clothed comfortable temp and, if so, how much clothing?

the scale which places zero degrees at the absolute coldest point is called Kelvin. It has the same degree divisions as Celsius does. "Absolute zero," or zero degrees Kelvin, is the coldest temperature possible.
So, if you are measuring in Kelvin, twice as cold is not possible.(0/2=0)

Absolute zero in Fahrenheit is -459.67. Thus, from zero degrees F, twice as cold would be -229.835 degrees F.
