what is absolute body temperature?

I recently, read the "absolute body temperature" concept, but can't remember what was it, exactly. Can somebody help?

I'm not sure absolute body temperature exists :?. Does it

I read about it, in my textbook.It is connected with Stephan-Boltzmann law. Remember, T^4=absolute body temperature.

I think what your textbook is saying is that the T in that equation is the temperature on the absolute scale (in degrees Kelvin) not the temperature in degrees C.

Isn't C absolute scale? Why the Kelvin's scale is said to be absolute?

I think because you can't go below absolute 0. Therefore Kelvins is an absolute scale. Celcius goes below 0, so its really difficult in calculations if you are constantly using negative numbers.

Read the wikipedia article on absolute zero, it explains it better than I would. And, it's not just the problem of working with negative numbers. The Stefan–Boltzmann law does not work unless you use absolute temperature.

The absolute temperature of a body is the temperature measured from absolute zero - the temperature at which all thermal movement of particles ceases. On this scale 0 degrees centigrade is equivalent to 273 degrees Kelvin (approximately).
As Harold says a much fuller explanation can be found in, for example, wikipedia.
Does that help?

What do you understand by absolute temperature? I sow a example in my text book, which says that the temperature of the skin is 33 C = 293 K, which is absolute temperature.

everyone has a different base body temperature take mine, I am quite hot for a human and run at 37.9C unless I am ill so to me everyone feels cold and I myself rarely feel cold outside. It just all depends on genetics and body fat etc.
