The Celsius, Fahrenheit, and Kelvin Temperature Scales


#1

Tc = T - 273.15

This Equation shows that the Celsius temperature Tc is shifted from the absolute (Kelvin) temperature T by 273.15°. Because the size of a degree is the same on the two scales, a temperature difference of 5°C is equal to a temperature difference of 5 K. The two scales differ only in the choice of the zero point. Thus, the ice-point temperature on the Kelvin scale, 273.15 K, corresponds to 0.00°C, and the Kelvin-scale steam point, 373.15 K, is equivalent to 100.00°C.

A common temperature scale in everyday use in the United States is the Fahrenheit scale. This scale sets the temperature of the ice point at 32°F and the temperature of the steam point at 212°F.

The relationship between the Celsius and Fahrenheit temperature scales is as follows in
the following equation

Tf = 9/5 Tc + 32
