Question
How is humidity measured?

Solution 1
Humidity is measured in grams per cubic meter. The air is considered to be dry when the humidity in the air is 0 gm/cu.m. Whereas the air is saturated when the humidity at 30°C temperature is 37 gms/cu.m.
Solution 2
Humidity is measured in grams per cubic meter (g/m3). Absolute humidity is the mass of water vapor in a unit volume of air. When there is no water vapor, the absolute humidity is 0 g/m3, and the air is considered completely dry. At 30°C, air reaches its saturation point when the absolute humidity is approximately 30.4 g/m3. This means that at 30°C, the air can hold up to around 30.4 grams of water vapor per cubic meter. If humidity exceeds this level, the excess water vapor condenses into liquid water (dew, fog, or clouds). It’s important to note that this maximum capacity for water vapor varies with temperature; warmer air can hold more water vapor, while cooler air can hold less.
