Here is the list so far: amp ampere "k" kilometer kilo kilogram kilo kilometer meg megaliter meg megohm klick kilometer (or km/h?) micron micrometer mil millimeter nit candela per square meter puf picofarad (pF)
As if anyone on this lists needs a reason, the multiple uses of "meg" and "kilo" is reason enough not to use such shortened versions. On the other hand, I don't see myself starting to say "three milliamperes" rather than "three milliamps." Jim Elwell
