According to a German story, Fahrenheit actually chose the lowest air temperature measured in his hometown Danzig (Gdańsk, Poland) in winter 1708/09 as 0 °F, and only later had the need to be able to make this value reproducible using brine.[16]
According to a letter Fahrenheit wrote to his friend Herman Boerhaave,[17] his scale was built on the work of Ole Rømer, whom he had met earlier. In Rømer's scale, brine freezes at zero, water freezes and melts at 7.5 degrees, body temperature is 22.5, and water boils at 60 degrees. Fahrenheit multiplied each value by four in order to eliminate fractions and make the scale more fine-grained. He then re-calibrated his scale using the melting point of ice and normal human body temperature (which were at 30 and 90 degrees); he adjusted the scale so that the melting point of ice would be 32 degrees and body temperature 96 degrees, so that 64 intervals would separate the two, allowing him to mark degree lines on his instruments by simply bisecting the interval six times (since 64 is 2 to the sixth power)

尼玛谁告诉你是这么来的,你去找那个傻叉
华氏温度最早是按照饱和盐水冰点定义的0度,去查查,大概零下32C因为这是华氏认知里的极冷
然后这个孙子还是个爱马人士,决定马体温为100(比人热和些)
标准化后才成现在这个样子

: 定义冰水混合物为32度
: 定义沸水为212度
: 全世界只有美国还在用如此搞笑的温度系统

妈蛋,为啥不说是猫的体温定为100度。LOL
这样养猫的都知道100度就高烧和猫一样热了。

低温看着挺严谨的
结果高温这么扯蛋
