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. |

We all owe Hairless at least a half hearted apology.- Hide quoted text - - Show quoted text - 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. |

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. |

Apparently, knots and meters are tied together, somewhat. 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. Casady |
