How to Use the WBGT Calculator

The Wet Bulb Globe Temperature (WBGT) Calculator is designed to calculate WBGT readings based on input temperatures and environmental conditions. WBGT is a measure used to estimate heat stress in direct sunlight, which is critical for ensuring safety in hot environments. Below is a step-by-step guide on how to effectively use this tool:

Step 1: Enter Dry Bulb Temperature

  • Locate the input field labeled “Dry Bulb Temperature (°C)”.
  • Enter the temperature value in degrees Celsius. It should be within the range of -50°C to 100°C.
  • Ensure the entered value adheres to the precision of one decimal point (e.g., 23.5).

Step 2: Enter Wet Bulb Temperature

  • Find the input field labeled “Wet Bulb Temperature (°C)”.
  • Input the temperature measured in degrees Celsius, ensuring it’s within the prescribed range of -50°C to 100°C.
  • The value should be entered to one decimal place for accuracy (e.g., 18.4).

Step 3: Enter Globe Temperature

  • Identify the input field labeled “Globe Temperature (°C)”.
  • Fill in the globe temperature in degrees Celsius. This value must also fall between -50°C and 100°C.
  • Maintain one decimal place precision (e.g., 31.7).

Step 4: Choose Environment Type

  • Locate the dropdown labeled “Environment Type”.
  • Select either “Indoor or No Solar Load” or “Outdoor with Solar Load” based on the environmental conditions you are measuring.

Understanding the Results

Once the above steps are completed, the calculator will compute the following:

  • Wet Bulb Globe Temperature (WBGT): This is calculated differently based on the environment type selected.
  • Risk Level: This categorizes the risk based on the WBGT value. The levels are as follows:
    • Low Risk: WBGT less than 18.0°C
    • Moderate Risk: WBGT from 18.0°C to just below 23.0°C
    • High Risk: WBGT from 23.0°C to just below 28.0°C
    • Very High Risk: WBGT from 28.0°C to just below 30.0°C
    • Extreme Risk: WBGT 30.0°C and higher

This process ensures you receive an accurate WBGT reading according to your specified conditions, helping assess heat risk effectively.
