Differences Between the new and old systems

• Wind speed is now calculated for 5 feet off the ground. Wind speed was previously based on observations at 33 feet.
• The calm wind threshold was lowered to 3mph.
• A consistent standard for skin tissue resistance is now in use.
• Measurements are based on how wind affects the human face, typically the most exposed portion of the body.
• The table incorporates the theory that heat is lost from the body depending on its surroundings
• The sun's impact is not factored into the wind chill temperature formula.
