  • Dew Point Calculator - Find The Dew Point

    Dec 08, 2020 · The dew point is 60°F (~15.5°C), so following the formula, we can find out that the relative humidity is ~60%. And now a paradoxical question: which of those two situations would feel more humid? Definitely the second one! The dew point is the value we should look at if we want to know how dry or humid it is outside, not the relative humidity.

  • Dew Point Calculator

    Dew is the condensed water that a person often sees on flowers and grass early in the morning. Dew point varies depending on the amount of water vapor present in the air, with more humid air resulting in a higher dew point than dry air. Furthermore, the higher the relative humidity, the closer the dew point to the current air temperature, with 100% relative humidity meaning that dew point is equivalent to the current temperature. In cases where dew point is below freezing (0°C or 32°F
