About RF Cafe

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...

Density of Some Common Building Materials

Building MaterialsWalker's Building Estimator's Reference BookThese values for density of some common building materials were collected from sites across the Internet and are generally in agreement with multiple sites. Most are from ASAE (American Society of Engineers and Architects) tables. However, if you have values that you believe are more accurate, use them for your calculations, and please send me an e-mail to let me know what your values are. Note that original units were lb/ft3, so actual number of significant places in kg/m3 column are the same as the original unit; i.e., aluminum density is really only known to three significant places even though four are presented.
