Agreed, and OP is now in fits of laughter as our brains are fried from his conundrum

You can't quantify hot and cold in such a way that you can meaningfully double them.

Not at all, that's just being numb with units of measurement.

It should be - what is twice as cold as 32f?

Well as 68f is room temperature (comfort) twice as cold should be -4f

Quite right; just testing :cool:

But the question is asking about differences in quantities which are dependant on scale.

but there is a definite end to the scale, it's like asking what's half the height of a 10m tower, the answer can be in feet meters etc it's the same.

0 C is not 0 in terms of temperature it's actually + 273 C

In one of those 4am thoughts a few years ago, I remember thinking how darkness and cold don't exist, they're just lower values of light and warmth.

Sort of, not really. light and heat are measurable manifestations of energy, darkness and cold are perception constructs created by the brain.

Isn't there also that thing where if you poor cold water over one hand and warm water over the other the brain cant tell which is which.

you can get warmth from 0c therefore it is not 'cold'

but assuming by 'twice as cold' you mean half the temperature then you do it by converting like people have shown.

+273 kelvin surely? :|

Only if you've been turned into a cherry flavoured popsicle by some unfortunate industrial accident. Warm and cold are relative to the measure.

On, or off, a conveyor belt?

-8.88888889 C after some googling

0c=32f
32f/2=16f
16f=(see above)

im having twice as lamb for dinner, just about to put it in the oven at 453.15 K

Are you sure that the 0.15 K will make a difference?

0 is just a point on a scale, nothing more. Why are you assigning the meaning of absolute zero to it?

warm and cold are not relative in physics. 0c is never 'cold'

'cold' is absolute zero but i dont think you would find many physicists describing something like this as 'colder' , 'warmer' etc. i would assume it would be 'lower temperature' 'higher temperature'

QlimaxUK · 9 Jan 2011 at 13:40

i have a question, how do you know a lot of people that do this? are you a scientist or something? if so, why don't you just ask them about it

because the op is asking whats half the temperature of 0c ?

if hes really asking 'twice as cold' then he needs to ask again because its not worded correctly

eg.

"Cold" is confusing in the same way that "short" or "small" is
confusing. If I say that I am twice as short as you, what I probably
mean is that I am half as tall as you. It isn't really a good way to
talk at all; it's best to say "half as tall" because it's less
confusing.

"Cold" is even more confusing than "short" because temperatures can be
negative, but height can never be negative (not the height of a
person, anyway). If "twice as cold" means "half the temperature"

No! 'Cold' is not a measurable construct, it has no definition, it is relative. Warm and cold are relative, humanistic constructs. They have no basis in science what so ever.
