I won't go into details but if you check my previous answers you'll find them.
Things can't mathematically calculated in this manner unless on an absolute scale. The only absolute temperature scales are Kelvin and Rankine.
Converting to °K (or °R) and doing the math means if it's 0 °F today and twice as cold tomorrow it will be 459.67 °F tomorrow. Strange but true.
(0F = 255.37K, 255.37 x 2 = 510.74K, 510.74K = 459.67F)

1. What UNITS are those degrees? Fahrenheit or Celsius? 2. What is meant by "twice as cold"? Do you mean half the absolute temperature? Or do you mean twice as much heat flux is leaving your body? Hopefully you don't mean half the absolute temperature, where 0 Celsius is 273.15 K, and thus half the absolute temperature is 136.575 K, which is -136.575 C. THAT IS COLD ENOUGH TO FREEZE YOUR SKIN OFF. Most likely, you mean "twice as much heat flux", because you cannot feel temperature. You can only feel heat flux. This is why you can touch a wooden box and a metal fork and think the metal fork is colder, even though they are both the same temperature. Grossly assuming that the modes of heat transfer off your skin are linear modes of heat transfer, this means that, heat flow off your body is given by the equation: Q_dot = (Tbody - T)/R where R is an assumed constant value called thermal resistance. So: Q_dot_today = (Tbody - Ttoday)/R Q_dot_tomorrow = (Tbody - Ttomorrow)/R Condition of the problem: Q_dot_tomorrow = 2*Q_dot_today Thus: (Tbody - Ttomorrow)/R = 2*(Tbody - Ttoday)/R Cancel R: Tbody - Ttomorrow = 2*(Tbody - Ttoday) Solve for Ttomorrow: Ttomorrow = Tbody - 2*(Tbody - Ttoday) Assuming you meant 0 Celsius, our data is: Tbody:=37 Celsius <<< standard human body temperature; Ttoday:=0 Celsius; Result: Ttomorrow = -37 Celsius

Oh thats simple -32 Degrees Fahrenheit.
If you take 0 Degrees FFahrenheit and convert to to Celsius you get -17.77778. take that number then multiple by 2 you get -35.55556. Then take that number and convert it back to Fahrenheit and you get -32 Degrees.

Not this one again. It comes up again and again. 125 times so far. It is silly and no one who knew what they were taking about would say it this way.

0F=255.22K
255.22K/2=127.61K
127.61K= -229.7F
Thats not going to happen.
