Most Americans can't even learn English, so to expect them to learn
the metric system is more than a stretch.

I don't think there is anything metric about knots. Metric would be km.

There *is* nothing about metric in "knots".

Unless you are a mathmetician or scientist...



Please explain. Last time I checked a "Knot" multiplied by 1.8
something, something, something equalled one kilometer per hour.

That's a knot ..... coverted to a metric unit.

What's the origin of a "knot"?

Apparently, knots and meters are tied together, somewhat. A nautical
mile is a minute of latitude. A meter is 1/10,000,000 of the distance
from the equator to the North Pole, and, obviously, a knot is a nautical
mile per hour. Thank you, wikipedia.

We all owe Hairless at least a half hearted apology.

Not at all.

The Knot is not (get it - Knot is not?) a metric measurement.

You cannot find the Knot listed as a base line definition of anything
in the metric system.

It is not a metric unit of measurement.

No, because a knot can be "tied together somewhat with any
measurement. It is NOT part of the metric system. But Hairy will act
like it was his intent.

He never stated that it was. According to Wikapedia the definition of a knot
has changed over time mainly due to the different standards of measure to
calculate same.
I'd give him credit for being half right even though he didn't know why.

Knots would be a speed. km might be metric, but it isn't a speed. its
a distance. There is a difference.

I've known a few European sailors. They measure wind speed in both
knots and meters/second depending on what wind instruments the boat
has. It turns out that knots are very closely approximated by
doubling meters/sec.

Meters and yards are absolutely tied together, by law. Exactly
25.4mm/inch. Not to mention that the meter is not defined in terms of
the size of the earth, as originally. You did say somewhat, which is
true.
