Frequently Asked Questions (FAQ)
What is the Dew Point Calculator (Air Temp & Relative Humidity) and how does it work?
Atmospheric physics, HVAC, and building inspection tool. Determines air saturation threshold temperature ($100\%$ relative humidity).
How do I use this Dew Point Calculator (Air Temp & Relative Humidity)?
Enter Air Temperature (°C or °F). Enter Relative Humidity (%) of indoor or outdoor air. View Calculated Dew Point and air mass comfort level.
What mathematical formula is used in this calculation?
Magnus-Tetens Approximation: Td ≈ T - ((100 - RH) / 5). Exact Equation: γ(T, RH) = (17.27*T)/(237.7+T) + ln(RH/100).
