Answer: Degree Celsius to Kelvin
Step-by-step explanation:
Temperature is the measure of degree of hotness or coldness. It is measured in units called as Kelvin (K) and degree centigrade .
The conversion factor is :

If 273 kelvin corresponds to

if the temperature is
, then the temperature in Kelvin will be
.
Thus the temperature when added 273 to the measured value is in Kelvin.
