They compare because relative humidity measures the maximum amount of moisture in the air.

Temperature and humidity are the measurements commonly used to assess the pleasantness of weather. These affect most how hot or cold it "feels" outside.

It is called the "relative humidity". The outside air today could have saturation (100% humidity). But is is actually 42% relative humidity. That's "how much there is compared to how much there could be".

Because it's about relative humidity, not absolutehumidity. Air can carry a certain amount of moisture dependent on which temperature it is, with warmer air being able to carry more before condensation occurs. If you have two volumes of air, both containing the same amount of water, then the warm volume will be a lower relative humidity than the cold volume.

Fog is basically visible water particles in the air. One of my sensors outside measured the humidity with the fog, I came out with 95% - 100%.

it starts to rain because if the humidity is high it is very moist outside so it rains

No, Humidity is when there is moist in the air. If it is high then there will be a lot of moist in the air. There for keeping them wet.

The heat index combines air temperature and relative humidity to determine how hot it feels outside.

Humidity meters are used to measure the humidity outside. Typically, these would be placed on the outside of your house to accurately measure the humidity.

How much moisture is in the air, and thus, how potent whatever the temperature is outside. If its 105 degrees F, but with a humidity level of 1%, I could maybe wear jeans. If its 105 degrees F, with a humidity of 20%, I could maybe die.

If the relative Humidity of a certain material or spot in your house is above 80 percent. You will get fungus and damp.

Humidity is the amount of water vapor in the atmosphere .Humidity is actually meant by relative humidity.There is also absolute humidity etc..Relative humidity is defined as the ratio of the partial pressure of water vapor in a parcel of air to the saturated vapor pressure of water vapour at a prescribed temperature.High humidity makes people feel hotter outside in the summer because it reduces the effectiveness of sweating to cool the body by reducing the evaporation of perspiration from the skin. Humidity is also greatly affected by intensity of solar radiation, altitude, wind exposure, cover and water status of soil.It is said that about 40% RH(relative humidity) is comfortable for human body. You can find more details about humidity on wikipedia .Follow the link -

It is a function of the "dew point" of the air at any given moment. If relative humidity is high, the dew point will also be high and the swamp cooler air will be relatively warm. If relative humidity is low, the dew point will also be low and the swamp cooler air will be relatively cold. A swamp cooler in Phx AZ will put out air about 30 degrees less than the outside air, and works more efficiently when the humidity outside is very low.

Relative humidity is a ratio between the partial pressure of water vapor and the saturation pressure of water vapor at the current temperature and pressure. If the temperature and pressure change, then the relative humidity will change also. You are correct that higher temperatures allow the atmosphere to hold more water. That means that the saturation pressure of water vapor has increased while the current vapor pressure has remained the same, causing the relative humidity to drop. We think of humidity as how hot and sticky it is outside. The closer the water vapor pressure is to its saturation point, the more hot and sticky we feel. We associate humidity with heat since that is when we are uncomfortable, but rain is caused by the relative humidity rising to 100% because the humid air cooled to the point that the saturation pressure dipped below the current vapor pressure (or other pressure changes, or a combination of both). You can learn more at the link below. I hope this helps.

Typically wet bulbs are used to give a heat-index or what it "feels like" outside. Because humans cool themselves by sweating, wet bulbs attempt to factor in humidity and wind speed to approximate the effective temperature while sweating. The wet bulb temperature is also used, together with the dry bulb temperature, to determine the relative humidity. If you know the relative humidity, you can calculate the difference with an equation given at: http:/

Humidity (RH) is a measurement of how much water vapor is in the air. When the humidity is high, that's when it feels sticky outside.

High humidity outside and a leaky house. What are you measuring your humidity with? Is it reliable?

The humidity outside is very high.ORDuring the summer the humidity in the air is usually higher than in winter.

North Carolina's humidity makes the temperature outside seem much hotter than it actually is. Humidity is moisture in the air.

if the humidity is wet we feel a bit cold and vice versa

You could say "The humidity outside is very high."During the summer the humidity in the air is usually higher than in winter.

Yes, it does when it's humid outside your hair will take the moister or water from the air. Which causes frizz and longer time to dry.

Relative humidity is the ratio of the amount of water air is holding to the amount of water it can hold. The warmer air is, the more water it can hold. Therefore, as air temperature drops, relative humidity increases, even when no additional moisture is being added to the air. If the temperature continues to drop after the relative humidity reaches 100%, the excess moisture gets condensed out of the air. That is why dew forms during the night. The cold cup of water cools the air around it by conduction, so that cooler layer of air in contact with the cup loses its ability to hold its moisture, and the excess moisture condenses onto the cup.

Because of the high humidity, the outside temperature felt much warmer than it actually was.
