Mechanical Units  Metric & SAE 
Here is a collection of
some of the most often used mechanical units. Both SI (metric) and SAE (English) units are given.
There
are two fundamental types of units: base units and derived units. Base units include meter, foot, kilogram,
second, etc. Derived units involve a combination of base units, such as square meter, kilometer/second, etc.

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
