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 Internet was still largely an unknown entity at the time and not much was available in the form of WYSIWYG ...

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 (cm^{2}) for metric

Square inch (ft^{2}) for SAE
