How embarassing! I really shouldn't be making corrections to my corrections, especially since Bill Potts already did it for me. But, that really should have been Pm for petametres. At least I wish I had not made a mistake that came out to be on olde English unit: Pt (pint) . So, if 1 light-year is equal to a pint, how many quarts are there in a parsec? :-) Regards, Bill Hooper physics professor (retired), Florida, USA ======================== Keep It Simple - Make It Metric! ========================
