What is Wet Bulb Temperature?
Wet Bulb Calculator: The wet bulb temperature is a measure of the lowest temperature that can be achieved through the evaporation of water. It reflects the moisture content of the air and is crucial in fields such as meteorology, HVAC, and agriculture. It is an important factor in understanding comfort levels, cooling requirements, and environmental conditions.

Formula of Wet Bulb Calculator
The formula to calculate wet bulb temperature is: TW = T * arctan[0.152 * (rh + 8.3136)^(1/2)] + arctan(T + rh) - arctan(rh - 1.6763) + 0.00391838 * (rh)^(3/2) * arctan(0.0231 * rh) - 4.686
Where:
- TW = Wet Bulb Temperature (°C)
- T = Current Temperature (°C)
- rh = Relative Humidity (%)
1. What is wet bulb temperature used for?
Wet bulb temperature is used to assess comfort levels in buildings, determine cooling needs in HVAC systems, and predict evaporation rates in agriculture. It is vital for understanding heat stress in both humans and livestock.
2. How does humidity affect wet bulb temperature?
Humidity significantly impacts wet bulb temperature. Higher humidity levels reduce evaporation, which lowers the cooling effect and increases the wet bulb temperature. This relationship is crucial for weather forecasting and comfort assessments.
3. Can wet bulb temperature be higher than the current temperature?
No, the wet bulb temperature cannot exceed the current temperature. It represents the lowest temperature achievable through evaporation, thus always being equal to or less than the ambient air temperature under typical conditions.
4. How do I measure relative humidity?
Relative humidity is typically measured using a hygrometer, which can be digital or analog. It indicates the current moisture content in the air compared to the maximum possible at that temperature, expressed as a percentage.
5. Why is the wet bulb temperature important in meteorology?
In meteorology, wet bulb temperature is essential for understanding atmospheric moisture content, predicting weather patterns, and assessing heat stress in humans and animals. It aids in weather forecasting and climate studies.
