The temperature is expressed on the celcius scale, in which the zero point is set at the ice point, defined as the equilibrium temperature of ice and air saturated water at pressure.Here, is temperature in degree Celsius and is temperature in Kelvin.There is another scale to measure temperature that is Fahrenheit which is related to degree Celsius as follows: ….. (1)Here, is temperature in degree Fahrenheit and is temperature in degree CelsiusRankine scale is the thermodynamic temperature scale in which temperature are denoted by degrees Rankine It is related to kelvin scale as temperature in Rankine is equals to 1.8 times temperature in Kelvin.From equation (1), the relation between temperature in Fahrenheit and Celsius is as follows:If temperature in Fahrenheit is equals to temperature in Celsius say it is equal to T so substitute T for both and thus,Rearrange,Or,Or,Therefore, temperature in degree Fahrenheit is equal to temperature in degree Celsius at value of temperature .
