About Humidity Measurements
Dew Point
The temperature to which air must be cooled to become saturated with water vapor.
Relative Humidity
The ratio of current water vapor to maximum possible vapor at that temperature.
Wet Bulb
The lowest temperature achievable by evaporative cooling at constant pressure.
Formulas Used
Dew Point Calculation
Td = (b × α(T,RH)) / (a – α(T,RH))
Where α(T,RH) = (a × T)/(b + T) + ln(RH/100)
(a = 17.27, b = 237.7°C)
Wet Bulb Approximation
Twb = T × atan(0.151977 × (RH% + 8.313659)^(1/2)) + atan(T + RH%)
– atan(RH% – 1.676331) + 0.00391838 × (RH%)^(3/2) × atan(0.023101 × RH%) – 4.686035

Weather Science FAQ
How does humidity affect weather patterns?
Humidity is a primary driver of weather systems. High humidity levels can lead to cloud formation and precipitation, while low humidity creates dry conditions. Our calculator helps quantify these relationships by providing precise measurements of atmospheric moisture content.
Why is dew point important in weather forecasting?
Dew point temperature indicates the air’s moisture content more reliably than relative humidity. When air temperature approaches the dew point, forecasters can predict fog, dew, or frost formation. This calculator provides accurate dew point calculations from various input parameters.
How do meteorologists use wet bulb temperature?
Wet bulb temperature is crucial for assessing heat stress potential and predicting minimum nighttime temperatures. It’s also used in calculating heat indices and designing cooling systems. Our tool implements the latest approximation formulas for accurate wet bulb calculations.
