What is the value of 1 kelvin?

Answer 1

Kelvin is the thermodynamic temperature (or absolute temperature) unit (S.I. unit).

One kelvin temperature interval is equal to one Celsius degree interval.

As interval, delta(T) = 1 K = 1oC.

e.g., "cool down a body 12oC" is equivalent to "cool down a body 12 K".

To find the equivalent Celsius temperature for a thermodynamic (or absolute) temperature in Kelvin, you have to recall that the "thermodynamic zero Kelvin temperature" ("absolute zero temperature") corresponds to -273.15oC. This and the

one-one interval relation gives you the following relation:

T(Kelvin) = T(Celsius degree) + 273.15

e.g., What is the equivalent absolute temperature in Kelvin for 20oC ?

T(K) = 20oC + 273.15 = 293.15 K ≈ 293 K

If you want to translate centigrade to Kelvin, from the previous relation you get:

T(oC) = T(K) - 273.15

e.g., What is the equivalent Celsius temperature for 500 K ?

T(oC) = 500 K - 273.15 = 226.85oC
