Nigel Parsons	BS: Celsius -Fahrenheit (51* d)	RE: BS: Celius -Fahrenheit	03 Apr 14
The theory I've heard is that the lowest temperature which could be considered as a constant was the freezing point of salt water/sea water. This was used as the starting point. Boiling (pure) water was used for the other endpoint. I don't believe that the Fahrenheit system was ever intended to have a specific meaning for 100 degrees. A scale of 180 degrees (half a circle) made much more sense as it allowed each degree to be smaller (giving amost double the precision) and allowed division by a greater number of factors.
