1. What is Corrected Effective Temperature?

Corrected Effective Temperature (CET) is a measure that combines air temperature and humidity to assess thermal comfort. It provides a more accurate representation of how hot it feels to the human body than temperature alone.

2. How Does the Calculator Work?

The calculator uses the Corrected Effective Temperature equation:

Where:

• \( T \) — Air temperature (°C)
• \( RH \) — Relative humidity (%)

Explanation: The equation accounts for how humidity affects our perception of temperature, with higher humidity making hot temperatures feel even hotter.

3. Importance of CET Calculation

Details: CET is important for assessing heat stress, designing comfortable environments, and planning outdoor activities in hot weather.

4. Using the Calculator

Tips: Enter temperature in °C and relative humidity in percentage (0-100%). Both values are required for calculation.

5. Frequently Asked Questions (FAQ)

Q1: What is a comfortable CET range?
A: Generally, CET values between 20-27°C are considered comfortable for most people.

Q2: How does CET differ from Heat Index?
A: Both measure perceived temperature, but CET uses a different formula and is more commonly used in certain regions and applications.

Q3: Why is 27°C used in the equation?
A: 27°C is the reference temperature where humidity starts to significantly affect thermal comfort.

Q4: Can CET be lower than actual temperature?
A: Yes, when humidity is below 50% at temperatures above 27°C, CET can be slightly lower than actual temperature.

Q5: What CET level is dangerous for health?
A: CET values above 32°C can be dangerous, especially for vulnerable populations like the elderly and children.
