How do I convert from kilometers into UK nautical leagues?
A nautical league is three nautical miles, which is 5.556 kilometers for the international nautical mile and 5.56 kilometers for the UK one.
Divide kilometers by 5.556, since a nautical league is three nautical miles of 1.852km each. 100 kilometers comes to just under 18 nautical leagues (17.998).
Type the kilometers into the Kilometers to UK nautical leagues calculator and it shows the step by step working underneath the result.
What is a kilometer?
A kilometer is 1,000 meters, or about 0.621 miles. 'Kilo' is the Greek-derived prefix for a thousand. It is the unit for road distances nearly everywhere except the US and UK, which still use miles.
A kilometer is about 3,281 feet or 39,370 inches. At a walking pace of 5km/h it takes about 12 minutes to cover.
Going from kilometers to meters just means moving the decimal point three places. A mile has to be broken into 1,760 yards or 5,280 feet first, and neither of those is a round number of anything.
What is a UK nautical league?
A UK nautical league is three UK nautical miles, ie 18,240 feet or 5,559.552 meters, which rounds to 5.56 kilometers. The international nautical league is slightly shorter at 5,556 meters.
Don't confuse it with the land league, which is three statute miles. The nautical league is three nautical miles, about 3.45 statute miles, so it's roughly 15% longer.
Britain's territorial waters once reached one marine league – three nautical miles – from the coast. The limit has been 12 nautical miles, or four leagues, since 1987.
