I sent Andy's recent posting about the increases in bandwidth and
potential prefixes to my scientist husband, and I thought the Netters
would enjoy his response....

--------------------------
Interesting...
A logical follow up is what are the prefixes when size decreases...

0.001 is milli- (1000 milligrams = 1 gram) (shorthand m)
0.00001 is micro- (1000 micrograms = 1 milligram) (shorthand µ)
0.0000001 is nano- (1000 nanograms = 1 microgram) (shorthand n)
0.000000001 is pico- (1000 picograms = 1 microgram) (shorthand p)
0.00000000001 is femto- (1000 femtograms = 1 picogram) (shorthand f)
Note- 1 femtogram of a substance is usually a manageable number of
individual molecules of that substance.

But what comes next?

It would also be nice to know what the abbreviation is for these new
units.  I assume P, E, Z, and Y (since G, M, and T are giga-, meta-, and
tera-).

Also the etymology- these are historically greek, are these new prefixes
greek or geek?
