(Fahrenheit zero is based on the commonsense measure of the freezing point
of a saturated salt solution which everyone has on hand, and boiling point
is 180 degrees above the freezing point of "pure" water. Completely logical
of course )

Correction: the F scale was based the freezing point of that solution
and set at 32 degrees. Then 100 was selected as the normal human body
temp, or that is what I heard, not sure). Just why they set the
freezing point at 32 vice 0 escapes me.

Maybe to help those unable to handle negative numbers, but still
needed a way to express temperatures below freezing?

Of course, the REAL 0 point (no heat at all) is considerably lower
than either 0C or 0F.
