The dry-bulb temperature (db) is the temperature of air measured by a thermometer freely exposed to air, but shielded from radiation and moisture. Dry-bulb records the amount of heat in the the air or the true thermodynamic temperature, and is measured in degrees Celsius (°C), Kelvins (K), or degrees Fahrenheit (°F).

Dry-bulb temperature is used in construction, as an important consideration when designing a buildings and a key indicator of occupant comfort.

Dry-bulb temperature is used in energy simulations, as an important metric of weather profiles for climates all over the world. It is most integral in creating psychrometric chart and determining thermal comfort.
