1. What is Dew Point?

Definition: The dew point is the temperature at which air becomes saturated with water vapor and dew begins to form.

Purpose: Knowing the dew point helps in weather forecasting, industrial processes, and preventing condensation problems.

2. How Does the Calculator Work?

The calculator uses the Magnus formula:

Where:

• \( T_{dp} \) — Dew point temperature (°C)
• \( T \) — Air temperature (°C)
• \( RH \) — Relative humidity (%)
• \( a, b \) — Magnus parameters (17.27 and 237.7)

Explanation: The formula relates air temperature and relative humidity to calculate the temperature at which dew forms.

3. Importance of Dew Point

Details: Dew point is crucial for understanding humidity comfort levels, predicting frost, and preventing moisture damage in buildings.

4. Using the Calculator

Tips: Enter the air temperature in °C and relative humidity in % (0-100). The calculator will compute the dew point temperature.

5. Frequently Asked Questions (FAQ)

Q1: What's the difference between dew point and humidity?
A: Humidity measures current water vapor, while dew point indicates the temperature at which condensation occurs.

Q2: Why does dew point matter in weather forecasts?
A: High dew points indicate muggy conditions; when close to air temperature, fog or precipitation is likely.

Q3: What's a comfortable dew point for humans?
A: Below 16°C (60°F) is comfortable, 16-18°C (60-65°F) is noticeable, above 18°C (65°F) is uncomfortable.

Q4: Can dew point be higher than temperature?
A: No, the dew point cannot exceed the current air temperature.

Q5: How is dew point used in industrial applications?
A: It helps control processes where moisture affects quality, like painting, drying, or pharmaceutical production.
