How many miles is 2 degrees longitude?
Each degree of latitude is approximately 69 miles (111 kilometers) apart.
How many nautical miles are in 1 degree of longitude?
60 nautical miles mile or 1 nm, equivalent to 1.582 km), so one degree (1°) of latitude corresponds to 60 nautical miles or approximately 111 km. The length of one degree (1°) of longitude varies because the meridians converge towards the poles. At the equator one degree of longitude is nearly the same as one degree of latitude (60 nm).
How many miles is 2 latitude?
approximately 69 miles The distance between any two latitudes is approximately 69 miles or 111 km. Latitude lines run parallel to each other. That's why the distance between them remains constant from the South to the North pole. On the other hand, longitude lines are furthest apart at the equator and meet at the poles.
How far is 1 degree of longitude at the equator?
60 geographical miles A geographical mile is defined to be the length of one minute of arc along the equator (one equatorial minute of longitude) therefore a degree of longitude along the equator is exactly 60 geographical miles or 111.3 kilometers, as there are 60 minutes in a degree.
How many miles is 5 degrees longitude?
Each degree of latitude is approximately 69 miles (111 kilometers) apart.
How do you convert miles into degrees?
To convert a mil measurement to a degree measurement, multiply the angle by the conversion ratio. The angle in degrees is equal to the mils (NATO) multiplied by 0.05625.
Why is a nautical mile different to a land mile?
Nautical miles are used to measure the distance traveled through the water. A nautical mile is slightly longer than a mile on land, equaling 1.1508 land-measured (or statute) miles. The nautical mile is based on the Earth's longitude and latitude coordinates, with one nautical mile equaling one minute of latitude.
Why is a nautical mile longer than a regular mile?
A nautical unit of length that, when converted into familiar land measurements, equates to 1.15078 land miles or 1.852 kilometres. The nautical mile is longer than a regular mile as it is based on the Earth's coordinates of longitude and latitude, with one nautical mile equal to one minute of latitude.
What is the 0 degree line of longitude called?
The prime meridian The prime meridian is the line of 0° longitude, the starting point for measuring distance both east and west around the Earth. The prime meridian is arbitrary, meaning it could be chosen to be anywhere.
How do you calculate distance using latitude?
If you treat the Earth as a sphere with a circumference of 25,000 miles, then one degree of latitude is 25,000/360 = 69.44 miles. A minute is thus 69.44/60 = 1.157 miles, and a second is 1.15/60 = 0.0193 miles, or about 101 feet.
How do you calculate distance using latitude and longitude?
For this divide the values of longitude and latitude of both the points by 180/pi. The value of pi is 22/7. The value of 180/pi is approximately 57.29577951. If we want to calculate the distance between two places in miles, use the value 3, 963, which is the radius of Earth.
Why do boats use knots instead of mph?
Cars and trains, known for shorter travel segments, use miles per hour or kilometers per hour. Boats and planes, which often travel longer distances affected by the earth's curvature, use knots. Knots are a more accurate way of predicting how a boat (or a plane) traverses the face of the earth.
Why is a mile called a mile?
It originated from the Roman mille passus, or “thousand paces,” which measured 5,000 Roman feet. About the year 1500 the “old London” mile was defined as eight furlongs. At that time the furlong, measured by a larger northern (German) foot, was 625 feet, and thus the mile equaled 5,000 feet.
How fast is a knot on a plane?
1.15 miles per hour Also known as a nautical mile, knots are measurements that planes and ships use to measure speed. One Knot per hour equals 1.15 miles per hour.
Why is Greenwich the Centre of time?
The decision was based on the argument that by naming Greenwich as Longitude 0º, it would be advantageous to the largest number of people. Therefore the Prime Meridian at Greenwich became the centre of world time.
Where is the exact place on Earth?
Any point on earth can be located by specifying its latitude and longitude, including Washington, DC, which is pictured here. Lines of latitude and longitude form an imaginary global grid system, shown in Fig. 1.17. Any point on the globe can be located exactly by specifying its latitude and longitude.
How do you add distance using latitude and longitude?
Add distance to a latitude or longitude
- Firstly, work out how many miles are in 1° of latitude, say for example it was 30.
- Then, divide one by it: 1 / 30 = 0.033333.
- Add it to my original latitude to get my maximum ° of latitude: …
- Subtract it to my original latitude to get my minimum ° of latitude:

Do planes fly in knots?
A typical commercial passenger jet flies at a speed of about 400 – 500 knots which is around 460 – 575 mph when cruising at about 36,000ft. This is about Mach 0.75 – 0.85 or in other words, about 75-85% of the speed of sound. Generally speaking, the higher the aircraft flies, the faster it can travel.
How did 12 inches became a foot?
The July 1959, international pound and yard agreement defined the international foot to be equivalent to 12 inches which were 1.7ppm (parts-per-million) shorter than the original United Kingdom definition and 2ppm shorter than that of the United States.
Why is it called a foot?
It is called a foot, because it was originally based on the length of a foot.
How fast do cruise ships go?
21 to 24 knots per hour Ordinary cruise ships travel at the speed of 21 to 24 knots per hour, but a high-speed cruise ship can go as fast as 30 knots or more. Most cruise ships are powered by diesel electric engines or gas turbines, and they have propellers that cut through the water to move them forward or backward.
Why use nautical miles instead of miles?
Nautical charts use latitude and longitude, so it's far easier for mariners to measure distance with nautical miles. Air and space travel also use latitude and longitude for navigation and nautical miles to measure distance. The word “mile” might leave you wondering if there's a “nautical kilometer,” too. There's not.
Where does time start in the world?
the Greenwich Meridian All time zones are measured from a starting point centered at England's Greenwich Observatory. This point is known as the Greenwich Meridian or the Prime Meridian. Time at the Greenwich Meridian is known as Greenwich Mean Time (GMT) or Universal Time.
Where does the day start in the world?
Each day on Earth begins at midnight in Greenwich, England, where the prime meridian is located. Originally, the prime meridian's purpose was to help ships at sea find their longitude and determine accurately their position on the globe.
In which body of water is 15?
The 15th parallel south is a circle of latitude that is 15 degrees south of the Earth's equatorial plane. It crosses the Atlantic Ocean, Africa, the Indian Ocean, Australasia, the Pacific Ocean and South America….Around the world.
| Co-ordinates | Country, territory or ocean | Notes |

What do you call an imaginary line that runs through the Earth?
The Equator is an imaginary line around the middle of the Earth. It is halfway between the North and South Poles, and divides the Earth into the Northern and Southern Hemispheres.
How do you find the distance between latitudes?
If you treat the Earth as a sphere with a circumference of 25,000 miles, then one degree of latitude is 25,000/360 = 69.44 miles. A minute is thus 69.44/60 = 1.157 miles, and a second is 1.15/60 = 0.0193 miles, or about 101 feet.
