Hello everyone, welcome to the astrogram class, in this issue, we will talk about the difference between absolute humidity and relative humidity. First, let’s understand the two concepts of humidity. Absolute humidity refers to the amount of water vapor contained in a unit volume of air; In grams. Relative humidity is the ratio of the actual water vapor content in the air to the saturation value water vapor content at a certain temperature, expressed as a percentage. Secondly, the difference between the two is that absolute humidity does not change with temperature and climate change, while relative humidity changes qualitatively with the increase in temperature and the decrease in temperature, and usually the relative humidity decreases as the temperature rises. If you want to measure humidity, you can first check whether you want to measure absolute or relative.
