Technically 0F is the freezing point of water, just a different type of water.
As a European I find Fahrenheit kind of makes sense on a human scale as 0 and 100 are the upper and lower limits of it being reasonable to be outside. Below 0 is "too cold", above 100 is "too warm" and when it is 50 it is neither warm or cold.
"Several accounts of how he originally defined his scale exist, but the original paper suggests the lower defining point, 0 °F, was established as the freezing temperature of a solution of brine made from a mixture of water, ice, and ammonium chloride (a salt)."
It's funny to use that rationalization regarding 0-100 when in reality the rest of the Imperial system is utterly allergic to that sort of scale. 0F and 100F being endpoints for "reasonable" seems a bit of a stretch as well. As a Canadian that's "reasonably cold" and "way too warm".
