You can't be twice as cold as zero degrees Celcius because Celsius measures temperature, not coldness.Kelvin is a better way of thinking about it as it has absolute zero as the coldest possible theoretical temperature although Kelvin is still a measure of temperature.I'm not aware of any scale of coldness which could quantify the concept of "twice as cold"
