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.
