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...

Coordinate System Conversions

There are three fundamental coordinate systems (rectangular, cylindrical, and spherical), each of which is a more convenient means for calculations depending on the configuration of your model. For example, mapping points on the surface of a sphere using the Cartesian coordinate system requires describing all three coordinates (x, y, and z) in terms distance from each of the threes axis references. Doing the same in the spherical coordinate system requires simply a radius and two angles. When you start doing very complex calculations like those requiring calculus applications, choosing the best coordinate system can make the difference between nightmarish equations and relatively simple ones.

Conversion formulas between the three fundamental coordinate systems are given below.

Here is a convenient online coordinate system converter on the Random Science Tools and Calculators website.
