Well, as I understand it, there is no definite method known, that
Fahrenheit used to calibrate his scale, other than noting things he
thought were hot or cold etc. On the other hand the Celcius scale has
precisely defined points, based on the Kelvin scale, which in turn
relates to temperature above absolute zero. The 0 & 100 degree points
originally referred to the freezing and boiling points of water, under
specified test conditions. Those points have been slightly revised to
bring the scale in line with Kelvin. Further, virtually all of the
measurement systems used in science are tied together through the metric
system, precisely defined and traceable back to some fundamental
constants. No such relationship exists in imperial measure, which often
varies around the world. i.e the U.S. and British gallons are different
sizes. There are different miles, depending on who does the measuring
and so on.
As far as the marks on the side of a thermometer go, there's no
difference, as the precision of either can be extended simply by using
more digits, provided the thermometer is capable of supporting that
precision. But to simply say the Fahrenheit scale is more accurate,
because there are more degrees on it is absolute nonsense.
