if today is 0 degrees,tomorrow will be twice as cold as today,how many degrees will be?

Answer 1

If you're speaking in Celsius:

-136.575°C.

First convert 0°C to Kelvin as Kelvin is an absolute temperature scale:

Absolute zero is equivalent to -273.15 C, so converting between K and C is a simple matter of addition or subtraction:

C = K - 273.15
K = C + 273.15

So 0°C is 273.15 Kelvin.

So, to find out what temperature (in degrees Celsius) would be ‘twice as cold’ (i.e. half the temperature) of 0°C, simply convert the value to Kelvin:

0 + 273.15 = 273.15K

Divide this value by 2:

273.15/2 = 136.575 K

and convert back to degrees Celsius:

136.575 - 273.15 = -136.575°C

Answer 2

Dumb question because temperature (Celsius or Fahrenheit) is NOT an absolute scale. So you can't measure "Twice as much". You need to convert to an absolute scale like Kelvin.

0 C is 273 K. Double would be 546 K.
0 F is 255 K. Double would be 510 K
0 K is well, 0 K. Double it and it'll be the same.

Answer 3

How cold you feel is dependent on wind, and the temperature differential between your body temperature and the air, and the heat capacity or something of air, which is alot less than most solids or water.

Total emmited energy is to the fourth power of absolute temperature, and the equilibrium temperature comfortable for people is around 21ºC which is a 21 degree difference from 0, and 2 to the inverse fourth power is 1.19, so 1.19 times the difference, subtracted from room temperature so.. um -4ºC would be my guess.

If you were in room temperature with very little clothing and went out into -4ºC cold, then you would feel twice as cold than if it were 0ºC, which seems about right.

If you're lifting weights or something in very little clothing then you could produce twice the energy and feel about the same as 0, or even warmer, depending on how hard you work.

However, if you stood out there longer with very little clothing until your skin temperature cooled down, you should lose heat at a deceleratingly slower rate, and the body even slows down metabolism so you lose heat even slower (when your living skin reaches 0ºC it starts freezing and frostbite, extremely painful)

So you should feel theoretically less cold as your skin cools down, but of course you feel colder, so you can't just treat any formula as if it were true.


All temperatures have to be corrected for wind chill.

And it's probably not possible to get frostbite in still air 1ºC or higher, but you can still get hypothermia even in very mild cold, if you stay there underclothed long enough.

You would feel several hundred times colder naked in Antarctican winter than at 0ºC. Does that mean you would freeze to death several hundreds of times faster?? I dunno.


True "half as cold" is on the 137K on the kelvin scale. It makes your body lose heat way way waaaaaaaaaaaay more than twice as fast though. You wouldn't feel twice as cold, you'd be dead.

Answer 4

When talking temperatures, you can only talk in terms of "twice the temperature" etc. if using an absolute scale of measurement. So, convert to degrees Kelvin and then do the sum.

Answer 5

0 degree celcius = 273 K
tomorrow's temperature will be 273/2 = 136.5k
tomorrow's temperature in degree celcius = 136.5 - 273 = -136.5 degree celcius

Answer 6

C or F
