On the Fahrenheit scale, do 0 and 100 have any special significance?

Short answer no, but Fahrenheit’s convoluted explanation of his scale is fascinating.

Did you know that Celsius was almost as loony? Today’s centigrade scale makes sense in that 0 is the freezing point of water and 100 is the boiling point, but that was decided after the death of Celsius. “The original Celsius scale had 100 for freezing, 0 for boiling. In other words, it was upside down.”

  1. The idea of having 64 units between two well known reference points, e.g. 32 degrees and 96 degrees, is that you can use simple tools to repeatedly halve 32, 16, 8, 4, 2 to one unit, and have it be an accurate scale. You can even do it by eye reasonably accurately.
