How much water is in the air at 80 humidity?
Weight of water vapor in air
| Water Vapor in Air (pounds water vapor per pound dry air) | ||
|---|---|---|
| Relative Humidity (\%) | Temperature | |
| 60 | 0.0020 | 0.0132 |

How do you calculate dew point from temperature and relative humidity?
Td = T – ((100 – RH)/5.) where Td is dew point temperature (in degrees Celsius), T is observed temperature (in degrees Celsius), and RH is relative humidity (in percent). Apparently this relationship is fairly accurate for relative humidity values above 50\%.
How do you calculate relative humidity in a room?
Divide actual vapor pressure by saturation vapor pressure and multiply by 100 to obtain a percentage using the formula Relative Humidity (percentage) = actual vapor pressure/saturated vapor pressure x100. The resulting number indicates relative humidity.
How does relative humidity vary with temperature?
Relative humidity changes when temperatures change. Because warm air can hold more water vapor than cool air, relative humidity falls when the temperature rises if no moisture is added to the air.

Is relative humidity directly proportional to temperature?
Relative humidity is inversely proportional to temperature. As relative humidity increases, less water evaporates from the surface of the skin, and evaporative cooling decreases. As a result, apparent temperature is greater than air temperature as relative humidity rises.
How does room temperature affect humidity?
As noted by the Sciencing.com website, “As air temperature increases, air can hold more water molecules, and its relative humidity decreases. When temperatures drop, relative humidity increases.”
