Just by definition in the SI naming convention.
No degree sign is used on the Kelvin scale.
hiiiiiiiiiiiii
A kelvin is larger. The kelvin "interval" is the same as a centigrade (celsius) degree
The SI unit of absolute temperature is the Kelvin, not the degree.
No.1 Kelvin degree is equal to 1 Celsius degree. Kelvin starts at - 273.15 oC but each degree has the same size Kelvin and Celsius.
K = C + 273.15 For 450oC, K = 450 + 273.15K = 713.15K (The degree sign is not used with Kelvin)
273.15 K (Note that the degree sign is not used with the Kelvin temperature scale)
0 Kelvin is -273.15 oCelsius. There is no negative portion on the Kelvin scale. 1 Kelvin degree has the same magnitude as 1 Celsius degree. If the temperature drops 15 K that is the same as dropping 15 oC Note Kelvin does not use the degree symbol.
There is no scenario where a Celsius degree is larger than a Kelvin degree since the Kelvin scale starts at absolute zero, which is -273.15 degrees Celsius. So, the value of 1 Kelvin is always larger than the value of 1 degree Celsius.
40 kelvin = -387.67 degree Fahrenheit.
The size of the degree is the same in the Kelvin and Celsius scales.
1 kelvin = -272.15 degrees Celsius.
