A convenient operational definition of '''temperature''' is that it is a measure of the average translational kinetic energy associated with the disordered microscopic motion of atoms and molecules.<ref> http://hyperphysics.phy-astr.gsu.edu/hbase/thermo/temper.html </ref>

Temperature is expressed in degrees. There are two units of temperature in common use - [[Celsius degree|Celsius]] (°C) and [[Fahrenheit degree|Fahrenheit]] (°F). Both make reference to the freezing and boiling points of pure water at normal atmospheric pressure.

Celsius (sometimes known as centigrade in the past) sets the freezing point at 0 degrees (0 °C) and the boiling point at 100 degrees (100 °C).<br>

Celsius (sometimes known as centigrade in the past) sets the freezing point at 0 degrees (0&nbsp;°C) and the boiling point at 100 degrees (100&nbsp;°C).<br>

Fahrenheit sets the freezing point at 32 degrees (32 °F) and the boiling point at 212 degrees (212 °F).<br>

Fahrenheit sets the freezing point at 32 degrees (32&nbsp;°F) and the boiling point at 212 degrees (212&nbsp;°F).<br>

Conversion of Fahrenheit to Celsius:  °C = ( °F - 32 ) x 5 ÷ 9<br>

Conversion of Fahrenheit to Celsius:  °C = ( °F - 32 ) x 5 ÷ 9<br>

Conversion of Celsius to Fahrenheit:  °F = ( °C x 9 ÷ 5 ) + 32

Conversion of Celsius to Fahrenheit:  °F = ( °C x 9 ÷ 5 ) + 32
