There are three Temperature scales in use today, Fahrenheit, Celsius, and Kelvin. The Fahrenheit Scale was developed by the German physicist Daniel Gabriel Fahrenheit (1686-1736). He originally took as the zero of his scale the temperature of an equal ice-salt mixture and selected the values of 30 and 90 for the freezing point of water and normal body temperature, respectively; these later were revised to 32 and 96, but the final scale required an adjustment to 98.6 for the latter value. Fahrenheit temperature scale is a scale based on 32 for the freezing point of water and 212 for the boiling point of water, the interval between the two being divided into 180 parts. The conversion formula for a temperature that is expressed on the Celsius(C) scale to its Fahrenheit(F) representation is:

F = (9 / 5) * (C + 32)
