Reference Data
The Wet Bulb Globe Temperature (WBGT) is a composite temperature used to estimate the
effect of temperature, humidity and solar radiation (globe temperature) on humans. It is used
by industrial hygienist, athletes and the military to determine appropriate exposure levels to
high temperatures. It is derived from the following formulas.
Outdoors
WBGT= 0.7 x WB + 0.2 x TG + 0.1 x DB
Indoors
WBGT= 0.7 x WB + 0.3 x TG
WB = Wet bulb temperature
TG = Globe temperature
DB = Dry bulb temperature
