Humidity is the concentration of water molecules existing as vapor. The actual measurement is "relative humidity" because it does not determine the volume directly, only the ratio of the volume compared to the maximum the air can hold at that temperature. This dtermines the amount of condensation that can occur if the air is cooled.
How close to 100 % saturation of moisture in the air that it actually is.
Humidity is normally measured and monitored at all temperatures.
It depends on where you are and what the conditions are like. humidty
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".
The property measured in grains is the amount of moisture in the air, known as humidity. Grains per pound (GPP) is a common unit of measurement for humidity in the air.
hygrometer
measured as humidity in the air with a hygrometer.
A device used to measure humidity is called a psychrometer or hygrometer.
Humidity is measured using a hygrometer, which measures the amount of water vapor in the air. Temperature and humidity are related but measured separately. The combination of temperature and humidity can be used to calculate the heat index, which is a measure of how hot it feels.
Relative Humidity is measured with a HygrometerHumidity is the amount of water vapor in the air.On hot days, when it feels sticky, the humidity would then be high.
I think rain is measured in millilitres (ml).
