<P> The Fahrenheit scale is a temperature scale based on one proposed in 1724 by Dutch - German - Polish physicist Daniel Gabriel Fahrenheit ( 1686 -- 1736 ) . It uses the degree Fahrenheit ( symbol : ° F ) as the unit . Several accounts of how he originally defined his scale exist . The lower defining point , 0 ° F , was established as the temperature of a solution of brine made from equal parts of ice , water and salt ( ammonium chloride ) . Further limits were established as the melting point of ice ( 32 ° F ) and his best estimate of the average human body temperature ( 96 ° F , about 2.6 ° F less than the modern value due to a later redefinition of the scale ) . The scale is now usually defined by two fixed points : the temperature at which water freezes into ice is defined as 32 ° F , and the boiling point of water is defined to be 212 ° F , a 180 ° F separation , as defined at sea level and standard atmospheric pressure . </P>
