Imagine you've just made yourself a thermometer by marking off the 0° and 100° points. Now delineate the 2° intervals, using only the tools you would have had available in the early 18th century.
Now imagine making a thermometer by marking off the 32° and 96° points (64° apart). Now delineate the 2° intervals.
Considering those two tasks, 64 seems a much better number to me (only have to divide unit lengths in half) than 100 (have to divide something by 5).

Great explanation, thanks.
