There was a similar question asked a few days ago. The question I'm afraid is meaningless. You cant double a measure of cold because cold is not a real thing - it implies an absense of heat - not its opposite.
You can have a temperature twice as hot or half as hot - and for that you're better off speaking in Kelvin but you cant have something twice as cold. If twice as cold means half as hot then I expect we will see most of the air condense as liquid nitrogen. Better put a scarf on.

If it was +5 yesterday, and zero today, then twice as cold tomorrow would be -5, you need to have more than one piece of data to make a proper comparison/calculation

Well, if it's 0, then it would be 0. 2 * 0 = 0.

That's preety easy. If it is 0ºC outside today, it means that are 32ºF. If it's supposed to be twice as cold tomorrow, the temperature, in ºF is 16ºF. By this formula, you can have the tempeature in ºC correspondent to 16ºF.
16= 32+1.8x(TºC),
16=32+ 1.8TºC
16-32=1.8TºC
-16/1.8=1.8TºC/1.8
-8.9= TºC.
So, if it's 0ºC today, the twice as cold will be -8.9ºC.
To Kelvin, you can use this formula:
TºK= TºC+273.15
TºK=-8.9+273.15
TºK = 264.25
So, if it's zero degrees today, the twice as cold tomorrow in Kelvin will be 264.15.

So you're obviously on the wrong site. According to the weather forecasters it's not even that cold in the far north of Scotland today.
Iceland ? - Oddly enough, I just had a look at your profile - and I was only one letter out !

Depends on how you judge the cold. 0 degrees celcius or fahrenheit ... convert to Kelvin ... and double it ... that would
be awfully hot. Twice as cold relative to what is the question you need to ask or the information you need supplied.

Actually it's 10.7 degrees C according to my thermometer.

-273 degrees (just joking)
i agree with the answer above.

if it is 0F, then twice as cold would be -227
if it is 0C, then twice as cold would be -137
