Relative Humidity (RH), is how much water vapor is in the air at a certain time. Humidity, in my opinion, is just another way of saying how much water vapor is in the air.

The amount of water that actually exists in the air at a given time?
Absolute humidity refers to the amount of water vapor that exists in a given volume of air at a given time. Relative humidity is absolute humidity relative to the maximum humidity for the current temperature.
What is a sygrometer?
There is no such thing as a sygrometer, but a hygrometer is a device that is used to measure the humidity of the air. It can indicate relative humidity or absolute humidity.
Measure of humidity?
Relative humidity and is expressed as a percentage. Absolute humidity is expressed as a concentration - mg/L. Specific humidity is a ratio of masses - water to air in a finite volume.
What are humidity measurements based upon?
Air humidity measurements are based on the water content of the air, expressed as volume percentage: Relative Humidity = percentage of saturation at a given temperature Absolute Humidity = percentage of water in the air, regardless of saturation or temperature. The humidity that is talked about in weather reports, is relative humidity.
Which is the comparison of the amount of moisture in the air to the amount of moisture it can hold?
relative humidity
Amount of moisture in air compared to amount needed in saturation?
Relative humidity.
What is the amount of water vapor in the air compared to the amount that could be in the air at that temperature?
relative humidity
What should the low and high end for humidity temperatures for your home?
30 to 50% of Relative humidity - the relative part of relative humidity being relative to the temperature.
What is the between humidity and relative humidity?
The ability for the atmosphere to hold water depends on a couple of factors, most notably being temperature. The hotter it is the more water can be absorbed by the air. Absolute humidity then is the total amount of water vapor contained in the air regardless of temperature. Relative humidity is the ratio to the amount of water the air is able to hold at a given temperature compared to the amount of water vapor it currently has (its absolute humidity). Assuming absolute humidity remains the same, and the temperature drops, then relative humidity will go up, meaning if there was already enough water vapor in the air at the previous temperature you might end up sweating more because the lower temperature might not be able to evaporate the same amount of sweat off your body.
What unit of measurement measures humidity?
Water vapor in the air is absolute humidity. The ratio of the absolute humidity to the maximum absolute humidity for that temperature and pressure is called the "relative humidity." Absolute humidity is very frequently expressed in terms of grains per pound of air, ppm, or vapour pressure. Relative humidity is usually expressed as a percent.Relative humidity, expressed as a percentage from 0% to 100%, is the amount of moisture in air divided by the total possible amount of moisture in air. Unfortunately, the total possible amount changes when the temperature changes, so the relative humidity can change without adding or removing any water.Another measure is dew point, which is the temperature at which water would condense. It doesn't change with temperature.The lowest measured relative humidity in Phoenix, AZ, USA, is 2%--pretty dry. Sometimes the dew point is below 0 degrees, also pretty dry. (Celsius or Fahrenheit? Both!)
What is the difference between absolute and specific humidity?
Relative humidity is a ratio of the actual water vapor content of the air to the amount of water vapor needed to reach saturation. Absolute humidity is the mass of water vapor contained in a given volume of air.
What is the average humidity in baton rouge la US?
