How to calculate wet bulb globe temperature
WebWet bulb globe temperature is an established heat index for determining workplace heat stress levels in order to reduce the risk of heat-related illness in workers (2,3). It is calculated from measured natural wet-bulb temperature, globe thermometer temperature, and dry bulb temperature (air temperature). WebThe following equations allow Relative Humidity to be calculated given the known parameters: Wet Bulb Temperature, Dry Bulb Temperature, and Station Level Pressure where U = Relative Humidity (%), T = Dry Bulb Temperature (°C), Tw= Wet Bulb Temperature (°C), P = Station Level Pressure (hPa)
