Figure 1.1 shows the Fahrenheit, Celsius, and Kelvin temperatures compared to the three

temperature scales. The Fahrenheit temperature scale is based on 32 °F for the freezing point of
water and 212 °F for the boiling point of water, with the interval between the two being divided

into 180 parts. The Celsius temperature scale is based on 0 °C for the freezing point and 100 °C
for the boiling point of water, with the interval between the two being divided into 100 parts. On

the Kelvin scale, 0 K represents absolute zero, the temperature at which the molecules of a
substance have their lowest possible energy. Accordingly, the Kelvin scale has become the

international standard for scientific temperature measurement.

Fahrenheit [°F] = [°C] × ⁄5 + 32 [°C] = ([°F] − 32) × ⁄9
Kelvin [K] = [°C] + 273.15 [°C] = [K] − 273.15
