  a qudt:Unit ;
  dcterms:description "The knot (pronounced 'not') is a unit of speed equal to one nautical mile (1.852 km) per hour, approximately 1.151 mph. The abbreviation $kn$ is preferred by the International Hydrographic Organization (IHO), which includes every major sea-faring nation; however, the abbreviations kt (singular) and kts (plural) are also widely used. However, use of the abbreviation kt for knot conflicts with the SI symbol for kilotonne. The knot is a non-SI unit accepted for use with the International System of Units (SI). Worldwide, the knot is used in meteorology, and in maritime and air navigation - for example, a vessel travelling at 1 knot along a meridian travels one minute of geographic latitude in one hour. Etymologically, the term knot derives from counting the number of knots in the line that unspooled from the reel of a chip log in a specific time."^^qudt:LatexString ;
