WBGT stands for which term?

• A. Wet Globe Temperature
• B. Globe Wet Temperature
• C. Bulb Wet Globe Temperature
• D. Wet Bulb Globe Temperature

Answer: (D)

WBGT is a heat-stress index that combines evaporative cooling, radiant heat, and air temperature into a single measure to assess environmental heat load on the human body. The term demonstrates the three components used: wet-bulb temperature (evaporation), the globe temperature (radiant heat), and the overall temperature measure. That’s why the expansion is Wet Bulb Globe Temperature. The other phrasings omit or rearrange one of these essential parts (for example, missing the bulb or mixing up the order), so they don’t represent the standard term. In practice, the index is calculated using a wet-bulb thermometer, a black globe thermometer, and a dry-bulb thermometer to capture the combined effects of humidity, radiation, and temperature on heat stress.
