Why is it that 6080 ft is equal to nautical mile?
A nautical mile is the length that represents one minute of arc (1/60 degrees) along any latitude or one minute of arc of longitude along the equator. Unfortunately, the earth is not a perfect sphere so the two measures are different. By international agreement, it has been set at 1,852 metres exactly - which is about 6076 feet (not 6080).
Why nautical mile is needed?
a nautical mile is a minute (1/60th) of one degree of the earths surface so it corresponds to maps
How many minutes are equal to 1.5 miles?
1 Nautical mile is 1 minute of latitude. Therefore 1.5 nautical miles is 1'30" (1 minute 30 seconds)
What distance is represented by one minute of latitued 60 minutes for each degree?
One minute of latitude represents 1 nautical mile
Is one mile on land different than one mile in water?
A2. YES. A nautical mile is exactly 1852m which is approx 6076 feet.[It was defined as a 1 minute of arc at the Equator, and this used to be considered 6080 feet, but a re-determination of the length round the equator gives us the lower number.]A land (Statute) mile is 5280 feet.
What is equivalent of 1 nautical mile?
1.1508 statute miles and one minute of latitude is equal to 1 nautical mile.
How many minutes is 0.30 miles?
Impossible to tell. However, if you are thinking 'nautical miles'. Then across the Earth's surface, 1 degree of arc is 60 nautical miles. Also 1 degree of arc is divided into 60 minutes. Hence 1 nautical mile = 1 minute. Each nautical mile is then divided into 60 seconds. So 0.30 nautical miles is 0.3 x 60 seconds 18 seconds of arc., A nautical mile is approximately 2025 yards of a (land) mile. So 18 seconds of arc is approximately, 0,3 x 2025 = 607.5 yards on dry land. NB 33.75 yards = 1 second of arc across the Earth's surface.
Why do you use nautical miles?
So if the statute mile is the result of Roman influences and plowing oxen, where did the nautical mile get its start? Each nautical mile originally referred to one minute of arc along a meridian around the Earth. Think of a meridian around the Earth as being made up of 360 degrees, and each of those degrees consists of 60 minutes of arc. Each of these minutes of arc is then 1/21,600th of the distance around the earth. Thus, a nautical mile is 6,076 feet.
Why is it that 6080 ft is equal to nautical mile?
A nautical mile is the length that represents one minute of arc (1/60 degrees) along any latitude or one minute of arc of longitude along the equator. Unfortunately, the earth is not a perfect sphere so the two measures are different. By international agreement, it has been set at 1,852 metres exactly - which is about 6076 feet (not 6080).

How many degrees of latitude equals 1 sea mile?
The nautical mile is approximately one minute, that is, 1/60 degree.
What is equivalent of 1 mile?
1.1508 statute miles and one minute of latitude is equal to 1 nautical mile.
How many minutes are equal to 1.5 miles?
1 Nautical mile is 1 minute of latitude. Therefore 1.5 nautical miles is 1'30" (1 minute 30 seconds)
How many minutes are in a hundred mile?
100 miles is approx 86.9 minutes [or arc]. 1 nautical mile was originally defined as the length subtended along a line of longitude by 1 minute [of arc]. Thus 1 nmi = 1 minute [of arc] Due to the earth not being a perfect sphere but a geoid, the length of a nautical mile would vary depending upon latitude; it has since been agreed to be exactly 1852 metres, ie 1 nmi = 1852 m (exactly) 1 mile = 1609.344 m (exactly) → 100 miles = 100 × 1609.344 m = 160934.4 m → 160934.4 m = 160934.4 ÷ 1852 nmi ≈ 86.9 nmi = 86.9 minutes [of arc] (≈ 1 degree 26 minutes 53.9 seconds)
One knot is how many miles per minute?
One knot is equal to one 'nautical' mile per hour. (A British nautical mile is equal to 6,080 feet, an International nautical mile is 1,852 meters.) It is also 1.151 miles per hour.
How many degrees of latitude is one nautical mile?
One nautical mile is equivalent to one minute of latitude. In terms of degrees, one nautical mile is approximately 1/60th of a degree of latitude.
Why are nautical miles different to land miles?
The definition of a nautical mile was originally based directly on 1 minute of arc. This means a nautical mile is approximately 1/60 of a degree of latitude. However, it is now equal to exactly 1,852 metres. Meanwhile, "land miles" or statute miles developed in a different system, and a statute mile has evolved to be equal to exactly 5280 feet.
