Well if you want to get picky, from the Defense Mapping Agency; DMA
Techincal Report: Supplement to Department of Defense World Geodetic
System 1984 (WGS84); Part II, Parmameters, Formulas, etc. WGS 84 is the
datum normally used in GPS. The following is the current standard.
1 nautical mile = 1852 meters (exact)
1 statute mile = 1609.344 meters (exact)
1 US survey foot = 1200/3937 meters (exact)
That makes a km = .621371192237334 (rounded off) statute miles so 5/8's
is off by a few feet ;-) ...LOL
Bet you didn't know I had that six inch report at my finger tips? Anyway
what I think I said was 6/10's not 3/4's or at lesat I meant to.
The old Heart of Dixie ride had a 100 kilometer ride -- it was 62
miles and sanctioned as a 60 mile ride with AERC, but the awards read
"100 Km".

imitate our masters
only because we are not yet masters ourselves, and only
because
in doing so we
learn the truth about what cannot be imitated.
