## How deep is a league of water?

At sea, a league is three nautical miles (3.452 miles; 5.556 kilometres).

## How is the distance to sea calculated?

Then, one degree can be split into 60 minutes, of which one minute of arc on the planet Earth is 1 nautical mile. One nautical mile is slightly more than a statute mile (1 nautical mile = 1.1508 statute miles). According to the English measurement system, a nautical mile is equal to 1.1508 miles, or 6,076 feet.

## Why don’t we use nautical miles on land?

Because longitude converges at the poles minutes do not equal nautical miles for very long on a longitudal plane but minutes of latitude remain constant. NASA uses nautical mile scale, yet land routes use linear measurements and some people try to confuse us further with kilometers.

## What is the 100 fathom curve?

## How do you calculate fathoms?

To convert feet to fathoms, multiply the feet value by 0.16666667 or divide by 6. For example, to convert 10 feet to fathoms, multiply 10 by 0.16666667, that makes 1.6666667 fathoms is 10 feet.
