English Statute Miles

"The international mile (and before 1959, the statute mile) is the distance typically meant when the word mile is used without other qualifying words (e.g. nautical mile, see below). The international and statute miles are both equal to 5,280 feet, but the international mile is defined in terms of the international foot (0.3048 m), while the statute miles of the various English-speaking countries were based on the national foot of each country. The (mostly obsolete) U.S. statute mile is based on the U.S. survey foot (which is exactly 1200/3937 m) and differs from the international mile by about 3 mm. [7]
The name statute mile originates from a Statute of the Parliament of England in 1592 during the reign of Elizabeth I. This defined the statute mile as 5,280 ft or 1,760 yards; or 63,360 inches.

Rhumblines

also rhumb lines or rumb lines, or loxodrome. "This line of constant bearing is called a Rhumb line. The word 'rhumb' (or sometimes rumb and it is the same in French though not very well known) comes from the name of angle measurement representing the 'point' on the old fashioned compass cards. There are 32 'rhumbs' in 360 degrees, hence a rhumb is 11 1/4 degrees." (Source: http://jacq.istos.com.au/sundry/navrhumb.html)
