The temperature is 0℃ today, and it is expected to be twice as cold tomorrow. What is the temperature tomorrow?

Kelvin (k) is the thermodynamic degree-day, which is equal to the thermodynamic temperature of the triple point of water (1/273 8+06). The above definition is based on the physical constant: the thermodynamic temperature Ttr of the triple point of water, and Tt r has reached an international agreement on 1967, which is exactly equal to 273. 16K.

+273. 16= kelvin → kelvin -273. 16= celsius.

So: 0 degree =373. 16K≈373K.

Tomorrow will be twice as cold as today: 373 k *1/2 =186.5 k =-86.5 degrees. The temperature tomorrow is: 86.5 degrees below zero.
