If it's zero degrees outside today and it's supposed to be twice as cold tomorrow, how cold is it going to be?

infinity below zero watch out

no but -1 degrees

You need to use an absolute temperature scale like rankine or kelvin.

Assuming that is 0 degrees F that correlates to 255 K

We need to figure out what twice as cold means also. I would say that if it's half the the temperature then it's twice as cold.

That means it would be: 255 K /2 = 127.5 K which is -233.77 F

Quite a drop huh?

0 0 Degrees

"Twice as cold" doesn't really have any meaning. (Neither does "half the temperature, if the temperature is zero - half of zero is zero.) Whoever is asking the question doesn't understand physics.

I was going to say "You'd have to approach that logically rather than mathematically," but I realised that there is no logical way really of answering that.

I have however found a couple of these websites which may help:

There really is no simple method. :(

Sorry! Bethan. x

-136.5 degrees Celcius

You need to use the Kelvin Temperature scale ;-)

If I could get paid a buck everytime someone asks this question, I'd be rich.
