>>13938904Current Fahrenheit is nonsensical. The scale Fahrenheit originally envisioned (before everyone peer pressured him into using shit like brine and boiling points in the calibration) was the triple point of water occurring at 32 F and the mean temperature of the human body at 96.
Human body temperature of a healthy adult only varies by about +/- 1F over the course of the day, so that means anywhere you can find ice and humans at any some point during the year (so everywhere outside of the tropics) you have two calibration points with 2^6 delineations between them, and an accuracy of within 2% for the scaling. Which would have been pretty goddamned great for the 1700s.
In this original scale you also get some nice, serendipitously round numbers for important quantities:
Absolute Zero: -440
Room Temp: +70
Boiling point: +205
