Since you specified a certain temperature (0 degrees) and stated that it was to be twice as cold the following day, then......

If one was to convert zero degrees F to Kevin and then factor down towards the cold end of the scale looking for a number that if doubled would equal zero degrees F. (twices a cold in one direction would be twice as hot in the other), then you might have a solution, providing you don't go off the bottom of the scale of Kelvin.

I would contend that 100 degrees Kelvin is twice as cold as 200 degrees Kelvin, just as 200 degrees Kelvin is twice as hot as 100 degrees Kelvin.
