The dew point is a more direct measure of moisture content in the air. What is the dew point of 65% humidity? The dew point cannot be directly determined from a percentage of humidity without knowing the temperature. However, at room temperature, a humidity of 65% might correspond to a dew point around 18-20°C (64-68°F).

There are 2 steps to solve this one.Dew Point Temperature is defined as the temperature at which air would have to cool (at constant pressure and constant water vapor content) in order to reach saturation. Dew points provide insight into the amount of moisture in the air. The higher the dew point temperature, the higher the moisture content for air at a …Using the chart, you can find the place where the orange 40°C dry bulb and the blue 54% RH intersect (red dot). This will tell you that your space has (pink) 25g of water per kg of dry air. If you move your eyes horizontally to the left and read along the 100% RH line, this means your dew point is ~28°C (yellow).Dew Point Definition. Dew Point Temperature (Td) Is the expected dew point in degrees Fahrenheit valid for the indicated hour. Dew point temperature is a measure of atmospheric moisture. It is the temperature to which air must be cooled in order to reach saturation (assuming air pressure and moisture content are constant).
Reference Table Page 12Dew is a natural form of water, formed as water vapor condenses. Dew, like the glistening drops on this grassy field in the U.S. city of Anaconda, Montana, forms as water near the surface of the ground is cooled to its dew point, the temperature at which water vapor condenses. The dew point varies by area …
