Fahrenheit has had a bad, bad, press over the centuries

It was, after all, the ORIGINAL centigrade temperature scale.

Celsius was a relatively late-coming plagiarist !

It may have been centigrade, but those hundred degrees were relative to
random temperatures (the coldest and hottest that Fahrenheit could achieve).
The freezing and boiling point of water are easier for a layman to
understand than the freezing point of saturated brine or whatever was used
for 100. OK, so freezing/boiling of water are fairly inexact, and will vary
according to pressure, and impurities in water.


I've always wondered: why is it that F and C are denoted as "degrees F/C"
whereas Kelvin (like all other physical units) is just "Kelvin" (not
"degrees Kelvin")?
