A term that refers to water vapor in the air.
The measure of moisture in the air. The ideal humidity for cigar storage is commonly agreed to be 68 to 72% relative humidity.
Relative humidity is a percentage of total air saturation by water vapor. The amount of water vapor that it takes to saturate the air (i.e. 100%) increases exponentially as temperature increases. When the temperature increases the percentage of total air saturation decreases and vice versa.

Generally, a measure of the water vapor content of the air. Popularly, it is used synonymously with relative humidity.
Water vapor content of the air. See absolute humidity, dew point, mixing ratio, relative humidity, specific humidity.
Water vapor or moisture present in the air is called humidity. This number is usually given as a percentage. This is a percentage of how much water vapor is present in the air at a given temperature. At 0% there is no moisture in the air. And at 100% the air cannot hold any more moisture – usually it is raining at 100% humidity. Warmer air can hold more moisture than colder air. That is why this is called the relative humidity. The amount of moisture in 50% humidity at 40 degrees is less than the amount of moisture the air can hold at 50% humidity at 70 degrees. When warm air comes in contact with a colder surface, such as a glass containing a drink with ice cubes or a cold window, water vapor from the air can start condensing on the glass or window. The temperature at which the condensation starts to happen for the relative humidity is called the dew point.

This can be done in the home oven as follows: Place a small metal pan of hot water on the bottom of the oven. Then place your dough loaves on the bottom rack, in your hot oven, and close the oven door. Follow the rest of your recipe. NOTE: If you have oven room, you may also place a clay brick in the pan.

The amount of water vapor in the air. (not to be confused with Relative Humidity)
The amount of water vapor in the air. The higher the temperature, the greater the number of water molecules the air can hold. For example: at 60 degrees F (15 degrees C), a cube of air one yard on each side can hold up to 4.48 ounces of water. At 104 degrees F (40 degrees C), the same cube of air can hold up to 17.9 ounces of water. Relative humidity describes the amount of water in the air compared with how much the air can hold at the current temperature. Example: 50% relative humidity means the air holds half the water vapor that it is capable of holding; 100% relative humidity means the air holds all the water vapor it can. At 100% humidity, no more evaporation can occur until the temperature rises, or until the water vapor leaves the air through condensation. Absolute humidity is the ratio of the mass of water vapor present in a system of moist air to the volume occupied by the mixture, that is, the density of water vapor.

1. Generally, some measure of the water vapor content of air. The multiplicity of humidity measures is partly due to different methods of measurement and partly because the conservative measures ( mixing ratio, specific humidity) cover an extremely wide dynamic range, as a result of the rapid variation of saturation vapor pressure with temperature. 2. Popularly, same as relative humidity.
