Special thanks to *Carl Rod Nave* (RodNave@gsu.edu) for this Unit Convertor written in 1998 (1st version, I changed the format much!).
And also Joshua E. Barnes of the University of Hawaii for some of the astronimical conversions.

I found the following on the foldoc website...

1. <*unit*> The standard metric prefixes used in the
__Système International__ (SI) conventions for scientific measurement.

Here are the SI magnifying prefixes, along with the corresponding binary interpretations in common use:

The abbreviated forms of these prefixes are common in electronics and physics.

When used with bytes of storage, these prefixes usually denote
multiplication by powers of 1024 = 2^{10} (K, M, and G
are common in computing). Thus "MB" stands for megabytes
(2^{20} bytes). This common practice goes against
the edicts of the __BIPM__ who
deprecate the use of these prefixes for powers of
two. The formal SI prefix for 1000 is lower case "k"; some,
including this dictionary, use this strictly, reserving upper
case "K" for multiplication by 1024 (KB is thus "kilobytes").

Also, in data transfer rates the prefixes stand for powers of ten so, for example, 28.8 kb/s means 28,800 bits per second.

The unit is often dropped so one may talk of "a 40K salary"
(40,000 dollars) or "2 meg of disk space" (2×2^{20} bytes).

The accepted pronunciation of the initial G of "giga-" is hard, /gi'ga/.

Confusing 1000 and 1024 (or other powers of 2 and 10 close in
magnitude) - for example, describing a memory in units of 500K
or 524K instead of 512K - is a sure sign of the __marketroid__.
For example, 3.5" __microfloppies__ are often described as
storing "1.44 MB". In fact, this is completely specious. The
correct size is 1440 KB = 1440 × 1024 = 1474560 bytes. Alas,
this point is probably lost on the world forever.

In 1993, hacker Morgan Burke proposed, to general approval on
__Usenet__, the following additional
prefixes: groucho (10^{-30}), harpo (10^{-27}),
harpi (10^{27}), grouchi (10^{30}). This would
leave the prefixes zeppo-, gummo-, and chico- available for
future expansion. Sadly, there is little immediate prospect
that Mr. Burke's eminently sensible proposal will be ratified.
