The Nautical Mile was originally based on a minute of latitude, but

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.

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.....

Isn't KPS "Knots per Hour" = "Knots"?


Knots per hour, would be a unit of acceleration because "knots" means
"nautical miles per hour". Knots per hour = "nautical miles per hour per
hour". We sailors only DREAM of acceleration....(c;

You can use knots per hour to measure deceleration, too... :-)
(or should it be furlongs per fortnight? I always started the engine
when the Loran-gave an ETE of 99 hours.)

Yeah, but "deceleration" usually means we just ran aground and sailors
never like to think about "deceleration"...(c;
