In HVAC (Heating, Ventilation, and Air Conditioning) applications, temperature is most commonly measured using Degrees Fahrenheit (°F) or Degrees Celsius (°C). These units are integral to assessing and controlling the thermal environment in residential, commercial, and industrial buildings.

Degrees Fahrenheit is widely used in the United States, where HVAC systems are prevalent, while Degrees Celsius is used in many other parts of the world, including Europe and other international contexts. Both units allow HVAC professionals to accurately determine temperature settings for heating and cooling systems, ensuring comfort and efficiency in climate control.

The other units listed are not suitable for measuring temperature in HVAC applications. Kelvin (K) is a unit of absolute temperature measurement commonly used in scientific contexts, while millivolts (mV) measures electrical potential and has no relation to temperature. Pascals (Pa) are used to measure pressure, which is also relevant in HVAC for airflow and duct pressure monitoring but not for directly measuring temperature.
