À propos de Wet Bulb Calculator
This free wet bulb temperature calculator determines the wet bulb temperature from dry bulb temperature and relative humidity using the Stull (2011) regression formula. Wet bulb temperature indicates the lowest temperature achievable through evaporative cooling and is critical for assessing heat stress, HVAC design, and outdoor safety.
Questions fréquentes
What is wet bulb temperature?
Wet bulb temperature is the lowest temperature air can reach through evaporative cooling. It accounts for both heat and humidity, making it a better measure of heat stress than temperature alone.
Why is wet bulb temperature important?
Wet bulb temperatures above 35°C (95°F) are considered dangerous because the human body cannot cool itself through sweating. It's also critical for HVAC cooling tower design and agricultural planning.
What formula is used?
This calculator uses the Stull (2011) empirical formula, which provides accurate wet bulb estimates from temperature and relative humidity without requiring iterative psychrometric calculations.
