Table 2 Equations used for the calculation of WCT and FFT[23]

From: Environmental conditions at the South Col of Mount Everest and their impact on hypoxia and hypothermia experienced by mountaineers

Parameters Equations
Wind chill temperature WCT = 13.12 + 0.621 * T 11.37 * V 0.16 + 0.3965 * T * V 0.16
Facial frostbite time FFT = ( 24.5 * ( 0.667 * V + 4.8 ) + 2111 ) * ( 4.8 T ) 1.668
  1. V is the wind speed (in kilometer per hour) and T is the air temperature (in degree Celsius). FFT, facial frostbite time; WCT, wind chill temperature.
