Wind chill describes how much colder it feels outside due to wind removing heat from exposed skin faster than still air would, and understanding it is important for outdoor safety in cold weather. This wind chill calculator computes the perceived temperature based on the actual air temperature and wind speed, using the standard wind chill formula used by meteorological agencies. It helps you understand the real risk of frostbite or hypothermia during cold, windy conditions, which can be significantly more dangerous than the air temperature alone suggests. Useful for outdoor workers, hikers, athletes, or anyone planning activities in cold weather to dress appropriately and stay safe.
