Asked in Temperature

If it is zero degrees outside today and it is supposed to be twice as cold tomorrow how cold is it going to be?

The zero points on both the Celsius and Fahrenheit scales are arbitrary. These are, therefore, interval scales which means that 2 deg C (or F) is not twice as warm as 1 deg C (or F). In the absolute scale for temperature, 0 deg C is 273.15 K and so twice as cold (or half as hot) would be 136.575 K = -136.575 deg C.
