    The Fahrenheit scale has only one point of reference for people and that is not 100.

    Fahrenheit (the scientist) determined 0° at the coldest stable temperature he could achieve with a mixture of water, ice and ammonium chloride, then set the mean healthy body temperature (as it was known at that time, modern measuring equipment is more precise) at 96° and then as a third reference set 32° as the freezing point of water.
    The reference points were later changed to 32° for water freezing and 180° higher at 212° for water boiling due to Anders Celsius work and influence.

    Everything about this looks just random and devoid of any logic. Celsius for his scale referenced the temperatures at which water changes state and Kelvin uses the Celsius scale but sets 0 at the point of literally no energy. Behind both is an idea easily to grasp.
