Please read as 0 degrees celcius

Scientists deal in absolute temperatures to calculate temperature changes (Kelvin or Rankine). However, weather forecasters likely use a temperature (twice as cold) that will cause you lose twice as much heat, and that depends on the wind and windchill factor too. Twice as cold may be subjective rather than scientifically objective.

An accurate forecast will never say it will be 'twice as cold'. This term is genrally used as a superlative to explain in laymans terms that it is likely to be quite a lot colder tomorrow than today. It is not intended to have any scientific basis.
I'm sure this question came up a few months ago...

sreenivas, 'twice as cold as today' can mean many things depending on what the forecaster wants to:
(i) if the forecaster is good in physics, pearlsawme's answer is the most correct, as 'feeling hotness or coldness' depends on the diff in temp. In this case, it'd mean the diff in temp (btw body and surroundings) would be twice, so tomm it'd be -37 deg C.
(ii) if the forecaster was just trying to refer to the temp, he'd mostly probably mean 16 deg F. (since 0 deg C = 32 deg F).
(iii) it couldnt be 0 deg C, otherwise he'd just say 'it'll be as cold as today'.
(iv) it couldn't be 136.5 K, as i don't think it has happened since the ice age!

Normal temperature of human body is 37 degree centigrade.
Today’s temperature is less by 37 degree centigrade; i.e. today’s temperature is zero.
Tomorrow it will be colder than today. It will be twice as cold as today. Tomorrow the temperature difference of the surroundings with the human temperature will be two times less than the temperature difference of the surroundings with the human temperature that prevails today.
37 - (2 x 37) = -37 degree centigrade.
Cold or hot is determined only with reference to the human normal temperature.

The answer would have to be -136.5 degrees C if the statement were to be absolutely true.
If the statement is relative to the average temperature for the time of year, then you would take the difference between the average temperature and 0, then double it, and subtract it from tomorrow's average temperature.

A weather forecast would not say this, since it is not a meaningful comparison. The only scientifically meaningful answer might be half as hot, or half the heat. In that case, gooda is correct with 136.5K.

it will depend on the temperature scale used. the standard unit for measuring temperatures is Kelvin, so we can convert 0 degrees into kelvin and try dividing it by two.

hey man, the forecast is not talking to scientists, .... they are talking to public, and naturally it is assumed that they will understand ''twice as cold'' as ''more and more cold'', we don't feel the value of temperature as a scale we just feel that this is cold and that is colder.

64*F when asking scientific questions, it is always a good idea to inform everyone of THE UNITS that we will be working in, like *F OR *C
