Scott & all,
As I have often admitted, my interest in SI-metric is because measuring
would be so much easier for everyone in all areas of life.
My modem is pretty good because on automatic this zipped along quite
quickly. Then I put it on manual and jotted down the light years, microns,
angstroms and fermis on a copy of Jim Frysinger's Prefix Compendium.
It appears that they used the word 'micron' for a micrometer
(�m) or 10 to the -6 power. Then 'angstroms' filled in at 10 to the -7, -8,
and -10 powers. Then fremis filled in at 10 to the -13 and -14 powers. Thus
one fremi is the same as one femtometer at 10 to the -15 power.
On the other end of the scale, light years were shown from 10 to the 16th
power all the way to 10 to the 23rd power. Obviously they didn't use 'exa',
'zetta', or 'yotta'.
Did they use SI with terms that I don't know to be SI? Or are they mixing
some of the earlier metric systems into this.
I know there have been threads before which discussed 'light years' and
'angstroms', but I don't recall 'fermis'. I hope that I am not suggesting
too technical a thread with this question, although perhaps I would
understand some of it this time around.
