How far is 1 degree of longitude at the equator?
How far is 1 degree of longitude at the equator?
At the equator for longitude and for latitude anywhere, the following approximations are valid: 1° = 111 km (or 60 nautical miles)
How do you convert degrees into miles?
As such, it is easy to convert latitude into miles. Divide the amount of miles by the degrees in a circle. The circumference of the earth along the equator is 24,901.92 miles, and there are 360 degrees in a circle. This results in about 69.2 miles.
How many degrees is a nautical mile?
Historically, it was defined as the meridian arc length corresponding to one minute (160 of a degree) of latitude. Today the international nautical mile is defined as exactly 1852 metres (6076 ft; 1.151 mi). The derived unit of speed is the knot, one nautical mile per hour….

How long does it take to pass 1 minute in longitude?
Each degree of longitude is sub-divided into 60 minutes, each of which is divided into 60 seconds. A longitude is thus specified in sexagesimal notation as 23° 27′ 30″ E. For higher precision, the seconds are specified with a decimal fraction.
How do you calculate longitude?
The Earth rotates one full turn (360º of longitude) in one day. It therefore turns one degree of longitude in 1/360th of a day, or every four minutes. To calculate your longitude, you therefore simply need to work out the time difference between noon at your location and noon at the Prime Meridian.
How many miles is 5 degrees longitude?
A degree of longitude is widest at the equator with a distance of 69.172 miles (111.321 kilometers). The distance gradually shrinks to zero as they meet at the poles. At 40 degrees north or south, the distance between a degree of longitude is 53 miles (85 kilometers).
How many nautical miles are in 1 minute?
One minute of latitude equals one nautical mile and degrees of latitude are 60 nm apart. The distance between degrees of longitude isn’t constant because they converge towards the poles.
How fast in miles is 10 knots?
Knots to Miles per hour table
| Knots | Miles per hour |
|---|---|
| 9 knots | 10.36 mph |
| 10 knots | 11.51 mph |
| 11 knots | 12.66 mph |
| 12 knots | 13.81 mph |
How long does it take the sun to pass longitude?
Answer: 4 minutes take time does one longitude take to pass by the sun.
How long does it take Earth to cover 15 longitude?
This rotation is a full 360 . So, in one hour, the earth turns 15 . Every four minutes, the earth has turned one degree.
What is difference between longitude and latitude?
Latitude implies the geographic coordinates that determine the distance of a point, north-south of the equator. Longitude alludes to the geographic coordinate, which identifies the distance of a point, east-west of the Prime Meridian.
How many longitude are there?
To measure longitude east or west of the Prime Meridian, there are 180 vertical longitude lines east of the Prime Meridian and 180 vertical longitude lines west of the Prime Meridian, so longitude locations are given as __ degrees east or __ degrees west.
How much is degree of longitude equal to in miles?
One-degree of longitude equals 288,200 feet (54.6 miles), one minute equals 4,800 feet (0.91 mile), and one second equals 80 feet. Illustration showing longitude convergence. Latitude distances remain constant.
How many degrees is one mile in longitude?
Since all lines of longitude converge at both the North and South poles, one mile (along an E-W route) covers more of a degree at 70 degrees latitude than the same mile does at 20 degrees latitude.
How many miles on Earth are equal to one degree of latitude?
Parallels of latitude when shown on a map can be used therefore to determine distance on the earth, as follows: Degrees — One degree of latitude equals 60 nautical miles (a nautical mile = 1.15 statue miles, or 6076 feet).
How many miles 0r km per one degree of latitude?
At the equator for longitude and for latitude anywhere, the following approximations are valid: 1° = 111 km (or 60 nautical miles) 0.1° = 11.1 km 0.01° = 1.11 km (2 decimals, km accuracy)
