I did, but then I stuck the result (of 0.0110574 meters) into Google
"0.0110574 meters to inches" to convert it into inches.  I guess if I
had thought about it 1.1 cm is also reasonable.  0.011 meters just
didn't strike me as anything useful.  I should have thought about it
more.

I believe my mistake the first time around was to use 1*10^-6 instead
of 1*10^-7, because I came up with about 1/3 of a foot (which is
approximately the length of 1*10^-6 degree of longitude in Tampa).  I
don't remember, because I came up with that several weeks ago, and
only the end result of 1/3 foot stuck in my head.
