Humidity vs. Moisture: What's the Difference?
Edited by Aimie Carlson || By Janet White || Updated on October 8, 2023
"Humidity" refers to the amount of water vapor in the air, while "moisture" denotes wetness or water content in a substance or object.
Key Differences
Humidity is a term that specifically pertains to the presence of water vapor in the atmosphere. It gives us a sense of how damp or dry the air feels. Depending on its levels, humidity can affect various aspects, including our comfort, the weather, and even the preservation of food. High humidity levels can make warm temperatures feel hotter, as our sweat doesn't evaporate as quickly, denying the body its primary cooling mechanism.
Moisture, on the other hand, is a broader term, encompassing the presence of water in any substance, not just in the air. It can refer to the wetness on a surface, the water content in a material, or the dew on grass. Whether we talk about the moisture content in wood, soil, or food, we refer to the amount of water or liquid present in that specific material or object.
It's important to understand that while all humidity denotes moisture (as it's about water vapor in the air), not all moisture relates to humidity. For instance, the moisture in a piece of bread isn't about the air's water vapor content but about the bread's water content. Conversely, when we discuss humidity, we are exclusively referring to atmospheric water vapor, without any indication of liquid water presence.
In various industries, both humidity and moisture are crucial parameters. For example, in agriculture, understanding soil moisture helps determine when to water crops. Similarly, monitoring room humidity is vital in spaces like museums to preserve artworks. Both terms, though related to water presence, serve different purposes and denote different phenomena.

Humidity
The content of water vapor in the air, expressed as a percent of the maximum amount of water vapor that the air can hold at the given temperature; also called relative humidity. The capacity of the air to hold moisture increases with temperature, so if the temperature changes without changing the absolute content of the atmospheric moisture, the relative humidity will also change.
