On this one site I saw about metric prefixes it has a list of some that are "bogus" http://pages.prodigy.net/pizzabagel/Trivia_MetricPrefixes.htm Thats the site (the bogus prefixes are on the far right at the top and bottom). What Im wondering is who made them up and why?

Probably scientists or mathematicians who were trying to come up with a prefix for a number they used frequently, but the prefix never caught on.

Either that, or math teachers who deliberately put them on tests to fool their students.

Some of them looked like mistakes people might have made at some point. dk being used for deka seems a possible choice if you didn't actually know to use da (which I didn't, but I don't think I've ever used deka). yotta and otta could be simple mistakes too.

The top three and bottom three are stranger, though.

What, no prefixes to represent googols (10^100) or googolplexes (10^googol)? How tame...

I've honestly never seen or heard of the "bogus" prefixes. Does anyone else recognize them?

The "bogus" ones are prefixes used in some context or another, but which are not officially recognized.

In addition to the official prefixes, I've heard of hepa- and micromicro- (and the old fashioned slang for micromicrofarad - mikey-mike).

I've seen both dk and D for deka-.

Seems likely, but it isn't: otta is for eight, and it follows the same logic as hepa, exa, peta (seven, six, five).
