<>The precision of science or the measuring of extremes (the cold of space or the heat of the sun).

the gas-equations:

PV = nRT
or
P1*V1 / T1 = P2*V1 / T2

hold true when "T" is measured in degrees Kelvin

this is true mainly because kelvin-zero degrees
is at "absolute-zero" .... and the temperature kelvin
is directly proportional to teh average kinetic energy of
the molecules under observation.

It makes the math work right.


There are other situations where temperature is measured
in deg kelvin as well. One that comes to mind is
wavelength of blackbody radiation being inversly
proportional to the (deg-K.)

Wien's Law:
lp = 2.898 x 10-3 / T



another has to do with "noise-factor" of an RF antenna
and Boltzmann's constant.

in fact, almost EVERY physics/engineering calculation
that involves temperature uses absolute temperature
(kelvin)

I use it especially to check the volume of a gas using the formula

pV = nRT where p is pressure, V volume; n number of moles an T is absolute temperature
But when you do advanced physics, you have to use it instead o Celsius in many cases

I think only scientists use kelvin for sciencey stuff.
