How many seconds of longitude are in one degree?
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, for example, 23° 27′ 30″ E. For higher precision, the seconds are specified with a decimal fraction. An alternative representation uses degrees and minutes, and parts of a minute are ...
How many degree are there in 1 longitude?
The primary unit in which longitude and latitude are given is degrees (°). There are 360° of longitude (180° E ↔ 180° W) and 180° of latitude (90° N ↔ 90° S). Each degree can be broken into 60 minutes (‘).
How many minutes are in one degree longitude or latitude?
Each degree can be broken into 60 minutes, and each minute can be divided into 60 seconds. Any given location can be described in terms of degrees, minutes, and seconds of longitude and latitude. What is the value of 1 degree longitude in minutes? Each degree of longitude is sub-divided into 60 minutes, each of which is divided into 60 seconds.
What is the maximum number of degrees longitude?
What Is The Maximum Number Of Degrees Of Longitude Possible? On the earth, the prime meridian passes through Greenwich, England. Longitude lines can take range up to +180 degrees (180 degrees east) and down to -180 degrees (180 degrees west). The +180 and -180 degree longitude coincidence directly opposite the prime meridian.
How many hours is in 1 degree of latitude?
60 minutes1 The latitude of a point on the Earth's surface is determined by the angle (ø) between the point and the equator, passing through Earth's center (Peter Mercator [Public domain], via Wikimedia Commons). One degree of latitude is divided into 60 minutes (').
How many meters is a degree of longitude?
How Far Is One Degree? Converting NASA's measurement of the Earth's radius into meters and substituting it in the formula for arc length, we find that each degree the radius line of the Earth sweeps out corresponds to 111,139 meters.
What is the length of longitude?
The distance around the Earth measures 360 degrees. The meridian that runs through Greenwich, England, is internationally accepted as the line of 0 degrees longitude, or prime meridian. The antimeridian is halfway around the world, at 180 degrees.
How many miles is 2 degrees longitude?
Each degree of latitude is approximately 69 miles (111 kilometers) apart.
How far is 1 degree of longitude at the equator?
60 geographical milesA 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 long is 1 minute of latitude?
One minute of latitude is defined as one nautical mile (1 naut. 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.
What distance is 1 second of latitude?
about 90 feetThere are 60 seconds to a minute, so 1 second of latitude is 1/60 mile or 5280/60 feet. That comes to about 90 feet. The distance corresponding to a second of longitude will depend on where you are. If you are at the equator, a circle of longitude is still the same 24,000 miles, so 1 second is again about 90 feet.
Where is 180 degrees longitude?
The international date line, established in 1884, passes through the mid-Pacific Ocean and roughly follows a 180 degrees longitude north-south line on the Earth. It is located halfway around the world from the prime meridian — the 0 degrees longitude line in Greenwich, England.
What is a degree of latitude?
degree of latitude. noun. measurement of distance from the equator. The first degree of latitude is 111 kilometers (69 miles), decreasing in size to points at the North and South Poles.
How many miles is 5 degrees longitude?
Each degree of latitude is approximately 69 miles (111 kilometers) apart.
How many km is a degree?
approximately 111 km1. The distance of each degree of latitude is approximately 111 km.
How does the Earth rotate 1 degree of longitude in 4 minutes?
It is because there are 360° of longitudes. The Earth takes 24 hours to complete one rotation or to cover 360°of longitudes. This means that the Earth covers 15° of longitudes every hour. Thus, one degree of longitude takes 4 minutes (1 hour = 60 minutes, divided by 15° per hour = 4 minutes per longitude).
How far apart is each degree of latitude?
Each degree of latitude is approximately 69 miles (111 kilometers) apart. The range varies (due to the earth's slightly ellipsoid shape) from 68.703 miles (110.567 km) at the equator to 69.407 (111.699 km) at the poles. This is convenient because each minute (1/60th of a degree) is approximately one [ nautical] mile.
How many nautical miles is a minute?
This is convenient because each minute (1/60th of a degree) is approximately one [ nautical] mile. A degree of longitude is widest at the equator at 69.172 miles (111.321) and gradually shrinks to zero at the poles. At 40° north or south the distance between a degree of longitude is 53 miles (85 km)
Is latitude parallel to longitude?
More useful information from the about.com website: Degrees of latitude are parallel so the distance between each degree remains almost constant but since degrees of longitude are farthest apart at the equator and converge at the poles, their distance varies greatly.
How many degrees of longitude are there?
There are 360 degrees of longitude (because meridians make Great Circles around the globe), and there are 180 degrees of latitude. To further specify exactly where to find anything on Earth, measurements are stated not only in degrees but also in minutes and seconds.
How many minutes are in a degree?
Each degree can be broken into 60 minutes, and each minute can be divided into 60 seconds. Any given location can be described in terms of degrees, minutes, and seconds of longitude and latitude.
How far is the equator from the longitude line?
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). The line at 40 degrees north runs through the middle ...
How many meridians are there in the world?
Longitude is defined as imaginary lines called meridians that run from the north to the south pole. There are a total of 360 meridians. The Prime Meridian runs through the Greenwich Observatory in England, the location agreed upon by a conference in 1884 to be 0 degrees.
How far is the equator from the tropics?
At the equator, the distance is 68.703 miles (110.567 kilometers). At the Tropic of Cancer and Tropic of Capricorn (23.5 degrees north and south), the distance is 68.94 miles (110.948 kilometers). At each of the poles, the distance is 69.407 miles (111.699 kilometers). This is rather convenient when you want to know how far it is between each ...
Which hemispheres does the equator divide into?
The equator, which runs in a circle around the center of the Earth, divides the planet into north and south hemispheres. Lines of latitude and longitude intersect, creating a grid that allows anyone in any location to pinpoint a geographic location.
Where does the 40 degree line go?
The line at 40 degrees north runs through the middle of the United States and China, as well as Turkey and Spain . Meanwhile, 40 degrees south is south of Africa, goes through the southern part of Chile and Argentina, and runs almost directly through the center of New Zealand.
