OK, I'm that stupid. I give up.
Apparently the units program on the unix machine may be broken.
Or, maybe it's trying to convert inches into milliliters ;-)
I'm going to be researching this. It may confuse other people
who might try to use that "units" program.
Please, stop calling me an idiot. I admit I made a mistake.
I'm trying to fix the thing that seems to have caused my
mistake. It may be between my ears, but I'm not sure, yet.
1 mil = one thousand headaches per inch.
