How do I convert UK Nautical Miles to UK Leagues?

What is a UK Nautical Mile?
The UK nautical mile was based on one minute of latitude, ie 1/60th of a degree. The Earth is not a perfect sphere, so a minute of latitude varies slightly with latitude, which is why a fixed length had to be chosen.
The UK nautical mile, also called the Admiralty mile, was fixed at 6,080 feet, which is 1,853.184 meters. That is 1.184 meters longer than the international nautical mile of 1,852 meters (6,076.11549 feet), which the UK adopted in 1970.
What is a UK league?
A UK league was three miles, or about 4.828 kilometers. The length of a league varied between countries and centuries – three miles is the English figure.
The league has long since dropped out of use in Britain and survives mainly in fiction. Seven-league boots, at three miles a league, would cover 21 miles a step.
