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.

i was taught that it was blood heat.


It was blood heat. Blood heat and the freezing point of a saturated
Sodium Chloride solution were, in Fahrenheit's time, pretty good
candidates for fixed points.

Later on Fahrenheit's scale was crunched to make 9 Fahrenheit degrees
equal to 5 Celsius degrees. Hence 98.whatever °F

Poor Fahrenheit - first plagiarised, and then run over by a JCB...
