How is sensible heat typically measured?

Sensible heat refers to the heat that causes a change in temperature of a substance without changing its phase. It can be defined and measured using different temperature scales, but the most common scales used in practice are Celsius and Fahrenheit.

Fahrenheit is one of the temperature scales used primarily in the United States, where it measures temperature based on a scale where water freezes at 32 degrees and boils at 212 degrees under standard atmospheric conditions. It is particularly useful in HVAC and refrigeration applications, where measuring temperature differences is critical for assessing sensible heat changes in air and refrigerants.

The other scales mentioned, such as Kelvin (which is an absolute temperature scale used mainly in scientific contexts) and Celsius (widely used globally), are valid for measuring temperature and thus can also be applicable for discussing sensible heat. Rankine, while also an absolute temperature scale similar to Kelvin, is less commonly referenced in refrigeration contexts. The choice of Fahrenheit is therefore favored in many practical scenarios, particularly those relevant to everyday use in North America.
