NAUTICAL MILES
The circumference of the earth Is divided into 360'degrees,
each degree containing 60 nautical miles, consequently the
circumference of the earth, viz. 131,385,456 feet divided by
21,600 (360 X 60) gives the length of a nautical mile, viz.
6,082-66 feet, which is generally considered the standard.
1 statute mile = 5,280 feet
1 degree „ = 69*121 statute miles.
The nautical mile and geographical mile are now accepted as
6,080 feet.
The small difference between the two values is as follows :
Based on 6,080 ft. Based on 6,082*66 ft.
1 nautical mile =1*15 statute mile = 1*152 statute mile
25 nautical miles = 28*78 statute miles = 28*8 statute miles
1 statute mile = *8684 naut. mile = *868 naut. mile
25 statute miles = 21*71 nautical miles = 21*7 naut. miles
1 kilometre = 0*62statute mile=1,094 yards=3,280*8feet
8 kilometres = 5 miles approximately.
The French, German and Austrian nautical mile is 6,076 feet
in length.
The knot is a measure ofspeed, the speed of one knot being a
speed of one nautical mile per hour.
To convert statute miles into nautical miles multiply statute
miles by 0*8684; to convert nautical miles into statute miles,
multiply nautical miles by T1515.
