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
