OK, I think by now we've all agreed the following:
- The issue is NOT displaying temperatures to the user, but a userspace
program reading them from the kernel. The userspace program itself can
do temperature conversions for the user if he/she wants.
- The most preferable units would be decikelvins, as the value can give a
relatively precise as well as wide range of numbers ranging from absolute
zero to about 6340 degrees Celsius ((65535 / 10) - 273) which is well
within anything that a computer can operate. It also gives us a good
base for all sorts of other temperature sensing devices.

Do we all agree on those now?
