Area Conversions

Area is commonly described as the extent of a two-dimensional surface enclosed within a specified boundary. Calculating area is fairly straight forward for well-defined regions, like regular polygons and symmetrical circles and ellipses. Finding the area for irregular regions requires the application of calculus. In fact, it is with the assistance of calculus that even a common formula like for the area of an ellipse is derived. 

Below is a table of commonly used area conversion factors.

 

Standard units = Square centimeter (cm2) for metric

About RF Cafe

Kirt Blattenberger - RF Cafe Webmaster

Webmaster:

    Kirt Blattenberger,

    BSEE - KB3UON

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 tying up your telephone line, and a nice lady's voice announced "You've Got Mail" when a new message arrived...
