What does WBGT stand for?

• A. Wet-Bulb Globe Temperature.
• B. Weather-Bound Global Temperature.
• C. Warmth-Balance Global Thermometer.
• D. Wet-Bulb Ground Temperature.

Answer: (A)

WBGT stands for Wet-Bulb Globe Temperature. It’s a heat-stress index that combines three environmental measurements—wet-bulb temperature (which reflects humidity and evaporative cooling), globe temperature (which captures radiant heat from the sun and surroundings), and dry-bulb air temperature. By weighting these together (commonly about 0.7 for wet-bulb, 0.2 for globe, and 0.1 for dry-bulb), WBGT provides a single number that better reflects how hot it feels to the human body than any single measure alone. This index is widely used to set safe work/rest cycles, hydration guidelines, and PPE decisions in hot conditions. The other proposed terms don’t correspond to the recognized name of this measure.
