Conversion of temperature from one scale into another temperature scale:

From Celsius to Kelvin scale:

              The temperature (T) on the Kelvin scale can be obtained by adding 273 to the temperature C on the Celsius scale. Thus

                       T (K)    =        273 + C     …………  (i)

 

From Kelvin to Celsius scale:

             The temperature on the Celsius scale can be found by subtracting 273 from the temperature on the Kelvin scale. Thus

                       C    =        T (K) - 273    …………  (ii)

 

From Celsius to Fahrenheit Scale:

             Since 100 divisions on the Celsius scale are equal to 180 divisions on the Fahrenheit scale. Therefore, each division on the Celsius scale is equal to 1.8 divisions on the Fahrenheit scale. Moreover, 0°C corresponds to 32°F.

                     F     =        1.8C  +   32    ………  (iii)

 

            Here F is the temperature on the Fahrenheit scale and C is the temperature on the Celsius scale.

 

DO YOU KNOW?

                  A clinical thermometer is used to measure, the temperature of the human body. It has a narrow range from 35°C to 42°C. It has a constriction that prevents the mercury to return. Thus, its reading does not change until reset.
