The old formula for the chart was derived in the 1940s by a method that noted the length of time required for a bottle of water to freeze under a variety of wind speeds and air temperatures. Since little was known about the thermal transfer properties of skin at the time, the chosen plastic container skewed the results. The old chart yielded a wind chill factor that was too low - by tens of degrees Fahrenheit in extreme cases. Using modern methods that involve bringing the skin of human volunteers to near freezing, a new formula - and new chart - was born in the year 2000. An example: A 20 °F day with 10 mph wind, now has a wind-chill rating of 9 °F instead of 3 °F. |

RF Cafe began life in 1996 as "RF Tools" in an AOL screen name web space totaling 2 MB. Its primary purpose was to provide me with ready access to commonly needed formulas and reference material while performing my work as an RF system and circuit design engineer. The World Wide Web (Internet) was largely an unknown entity at the time and bandwidth was a scarce commodity. Dial-up modems blazed along at 14.4 kbps while typing up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived... All trademarks, copyrights, patents, and other rights of ownership to images and text used on the RF Cafe website are hereby acknowledged. My Hobby Website: AirplanesAndRockets.com
