6076.11549 US feet, approximately, according to Bowditch.



I believe that the nautical mile is based on the minute of LONGITUDE not
latitude. Longitude doesn't vary with changes in latitude (or attitude).
That's why when you are using paper charts (remember those) you measure
the distance with your dividers on the longitude scale on the east or west
side of the chart.

Where do you guys get this?? You have it 180 degrees backward. Or, is this a
troll? :-)

What? Longitude doesn't vary with latitude??????
Are you also saying that Latitude DOES vary with regards to
longitude??????

Agree.. that's what they taught us in the Power & Sail Squadron courses.

ROTFL!!!

I wonder what that would be in Ferengi units of measure.

Or Vulcan units of measure.



For Vulcan measurments check out these great Vuls ! The BB team is a
bit rough but gotta love the VB team!!!!! At least I do.

Also be advised that Ferengi Rule of Acquisition No. 6 requires:
Every vessel shall at all times proceed at a safe speed measured in KPH
so that she can take proper and effective action to acquire, take, or
possess anything of value appropriate to the prevailing circumstances
and conditions.

When did the online car insurance people get involved with contracting
measurements?

ooops...I'd better dig out those old textbooks & review.
Of course, that scale we measure on the left & right sides of the chart
are the latitude scales.

Hmmmmm..... I think you have your terms "Wrapped around the Axle"
here.... Nautical Miles is based on "Minute of Latitude" which does
NOT change since the distance from the Equater to the Poles is ALWAYS
the SAME, from any place on the EQUATER. Therefor, when dividing that
distance in Degrees, MInutes, and Seconds, will ALWAYS produce the same
Unit Lengths. Where as Longitude is the cicumfrence of the earth at
the equater divided into Degrees, Minutes, and Seconds, and that DOES
change Unit length as you move closer to the Poles. Longitude is marked
on the bottom and top of Maps, where Latitude is marked on the right and
left had edges of Maps. One ALWAYS uses the Latitude markings for
distance because they do NOT change Unit Length, EVER.....
