According to Wikipedia Fahrenheit is not based on that, but on the freezing point of brine (0 degrees F) and an approximation of average human body temperature (100 degrees F).
Fever is not measured with 2 decimal accuracy. Generally, 38 = mild fever, 39 = high fever, 40 = fucking high fever. Temperature meters still do show in 0.1°C accuracy because why the fuck not
Edit: according to wikipedia normal human body temperature is 97.7–99.5 °F or 36.5 - 37.5 °C
Also as someone mentioned below, it has nothing to do with hottest/coldest day recorded (Though that would be even worse)
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). The other limit established was his best estimate of the average human body temperature, originally set at 90 °F, then 96 °F (about 2.6 °F less than the modern value due to a later redefinition of the scale).
Fahrenheit is “how hot is it in a scale from horse piss to rat dick?”. Arbitrary scale based on nothing
As an American, my favorite temperature is lukewarm paint

That’s such a stupid statement.
