Both length and velocity are measured in knots; in the former case, it is equivalent to a Nautical mile; in the latter, to a Nautical mile per hour.

A knot consists of a length of one or more ropes, coiled through themselves in a way to produce a structural altering the characteristics of the rope. Knots may be used for fastening ropes to other structures, other ropes, or to let a rope slide along another rope. Knots are instrumental in sailing and climbing, and many other activities.

Knots are often classified as loop, bend, whipping, decorative and hitch.

descriptions and tying instructions should be added

In knot theory, a knot is an embedding of a circle in 3-D space, considered up to deformations (isotopies). This is basically equivalent to a conventional knot with the ends of the string tied together to prevent it from becoming undone. In higher dimensions, circles are unknotted anyways, so one considers embeddings of spheres and hyperspheres.
