About Dew Point Calculator
What is Dew Point?
The dew point is the temperature at which air becomes saturated with water vapor and condensation begins to occur. At the dew point, the relative humidity reaches 100%. Understanding dew point is crucial for predicting fog, frost, condensation, and other weather phenomena.
Key Points About Dew Point
- Dew point is always equal to or lower than the actual air temperature
- When temperature drops to the dew point, condensation forms on surfaces
- Dew point is independent of temperature but depends on humidity and pressure
- Higher dew point indicates more moisture in the air
Real-World Applications
- HVAC systems: Predicting when to use dehumidifiers to prevent condensation
- Agriculture: Forecasting frost and planning irrigation
- Industry: Preventing condensation on equipment and products during storage
