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"?

Eisboch

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.
