To convert from dew point to absolute humidity, you need to know the temperature of the air. The formula to calculate absolute humidity is: Absolute Humidity = 216.7 * (e/(T + 273.15)), where e is the vapor pressure at the dew point temperature and T is the temperature in degrees Celsius.

What is the amount of water vapour per unit volume of air called?
The amount of water per unit air is called, I believe the Absolute Humidity, and this is closely related to dew point. If the amount of water in a parcel of air remains constant, the temperature and relative humidity can vary all over the place, but the absolute humidity is constant and so, I believe, is the dew point.
Why isn't dew point always the same?
The dew point can vary because it is dependent on the air's temperature and humidity levels. When the temperature changes or when more moisture is added or removed from the air, the dew point will change accordingly. Temperature and humidity fluctuations can cause the dew point to fluctuate as well.
What is the relative humidity when the air is at its dew point?
100%
How are temperature and dew point associated?
The closer they are together the more humid it is.
What is the relative humidity when the air temperature is at its dew point?
It is 100%.
What is the only way to change dew point?
to change dew point, humidity must be changed. an increase in humidity will result in a higher dew point and vice versa.

What is the dew point a mesurment of?
The Dew Point is a measurement of the water vapor in the air … the Humidity.
How is dew point different from condensation?
the realationship between condensation and dew point is that condensation occurs when it reaches the dew point.
What is the temperature at which air can no longer hold all the water vapor?
That's an approximate definition of saturation. And the temperature at which the current amount of water vapor in the air would be the saturation point is called the dew point. The dew point is a measure of absolute humidity.
How do you use the words dew point in a sentence?
With with a dew point of 79 degrees the humidity was almost unbearable.
What is the relative humidity when the air is at its dew point?
100%
What are the two different degrease in humidity called?
I know there is relative humidity (the amount of moisture in the air) and dew point (the temperature in which dew is formed) they both fit in with humidity.
Describe what happens when air is cooled to its dew point?
When air is cooled to its dew point, it reaches a temperature at which its water vapor condenses into liquid water. This forms tiny water droplets which ultimately become visible as fog, mist, or dew on surfaces. Dew point is the temperature at which the air becomes saturated with water vapor and cannot hold any more, leading to the condensation of excess vapor.
Why is the dew point never the same?
The dew point is the temperature at which a given parcel of humid air must be cooled, at constant barometric pressure, for water vapor to condense into water. The condensed water is called dew. The dew point is a saturation temperature.The dew point is associated with relative humidity. A high relative-humidity indicates that the dew point is closer to the current air temperature. Relative humidity of 100% indicates the dew point is equal to the current temperature and the air is maximally saturated with water. When the dew point remains constant and temperature increases, relative humidity will decreaseTherefore, by the above stated reasons (of humidity and barometric pressure and saturation based on temperature) are all reasons the point at wick dew forms is not the same because the regions them selves vary and thus these relative factors maybe dissimilar.
How are temperature and dew point associated?
The closer they are together the more humid it is.
