Answer:
Wind chill relationships are not linear. The colder the temperature, the more strongly the wind chill factor is felt. At a wind speed of 31 mi/h (50 km/h), for example, the perceived temperature at 32°F (0°C) is 7°F (−14°C), but at −40°F (−40°C), the perceived temperature is −112°F (−80°C).
