one degree of longitude at the equator = 111.319 km. Decimal degrees (DD) express latitude and longitude geographic coordinates as decimal fractions of a degree.DD are used in many geographic information systems (GIS), web mapping applications such as OpenStreetMap, and GPS devices. 3. One degree of latitude is approximately 69 miles. 2. km — Distance in kilometers numeric array. 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. There's a simple approximative formula to find the length in km of 1° of longitude in function of latitude : 1° of longitude = 40000 km * cos (latitude) / 360 (and of course it gives 111 km for latitude = 90°). Rainier (47' N) Solution: 47° - 38.5° = 8.5° And 8.5° X 69 Miles = 586.5 Miles And 8.5° X 111 Km = 943.5 Km Your Turn! Degrees of latitude are divided into 60 minutes. Decimal degrees are an alternative to using sexagesimal degrees (degrees, minutes, and seconds - DMS). On the other hand, a change of 1 degree in longitude corresponds to a different distance, depending on latitude. Input Arguments. Distance in kilometers, specified as a numeric array. Data Types: single | double. Anonymous. The polar radius is 6366.8 km. Two cities are 340 km apart. At any latitude, 1 degree of longitude is roughly (111.1 km) x (cosine of the latitude). Question: Because The Distance Spanned By A Degree Of Latitude Is Nearly Constant, You May Use 1° Latitude = 69 Miles (111 Km) In The Following Problems. – whuber Oct 27 '10 at 21:38 4 So with the formula if I wanted to move +100m in the y direction from say 10.0 N, 10.0 E, would I just add 100 / 111111? (at N pole, the change is essentially 0. At Baltimore ( latitude = 39.48^o N), this length is 111.16 km, nearly. 111 km; 321 km; 211 km; 91 km; Answer. Die geographische Breite (B oder φ), auch geodätische Breite oder Breitengrad genannt (lateinisch latitudo, englisch latitude; internationale Abkürzung Lat. One degree of latitude, and one degree of longitude along the equator only, is equivalent to roughly 69.1 miles (111 km). 1 decade ago. So, if were lost at sea, at the Equator and were able to signal your coordinates in a Mayday call, and were correct to within 1° of latitude and longitude, the search would be looking at an area of over 12,000 sq km! 110.574 km: 111.320 km: 15° 110.649 km: 107.551 km: 30° 110.852 km: 96.486 km: 45° 111.132 km: 78.847 km: 60° 111.412 km: 55.800 km: 75° 111.618 km: 28.902 km: 90° 111.694 km: 0.000 km: Cos φ decreases from 1 at the equator to zero at the poles, so the length of a degree of longitude decreases likewise. With this value for R the meridian length of 1 degree of latitude on the sphere is 111.2 km (69.1 statute miles) (60.0 nautical miles). The length of 1 minute of latitude is 1.853 km (1.151 statute miles) (1.00 nautical miles), while the length of 1 second of latitude is 30.8 m or 101 feet (see nautical mile). deg = km2deg(340, 'mars') deg = 5.7465. Each degree of latitude is approximately 69 miles (111 kilometers) apart. collapse all. Longitude specifies the earth-west position. Remember that latitude lines are parallel to each other so the distance between them remains almost the same. 1 degree of Longitude = ~0.79585 * 69.172 = ~ 55.051 miles. The first decimal place is worth up to 11.1 km: it can distinguish the position of one large city from a neighbouring large city. 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. Assuming you mean on the surface of the Earth, 1 degree latitude is equivalent to about ~111km (you can do the maths to work out 1 km). At the equator, 1^oarc length = 111.32 km, nearly. The equator is 0°, the north pole 90°, and the south pole -90°. To be even more precise, those minutes are divided into 60 seconds. Enter Meters: or Arc-Seconds: Enter Latitude: m km arc-seconds arc-minutes degrees Calculate Meters Calculate Arc-Seconds. The length of a degree of arc of latitude is approximately 111 km (69 miles), varying, because of the nonuniformity of Earth’s curvature, from 110.567 km (68.706 miles) at the Equator to 111.699 km (69.41 miles) at the poles. The distance of each degree at the equator is 110.567 km. Answer (1 of 7): The most common way to locate the points on the surface of the earth is by the geographic coordinates called latitude and longitude. Also remark that 1… Thanks for A2A The 1 degree of latitude is located above equator and the distance from equator is approximately 111 kms. At 38 degrees North latitude: One degree of latitude equals approximately 364,000 feet (69 miles), one minute equals 6,068 feet (1.15 miles), and one-second equals 101 feet. The first decimal place is worth up to 11.1 km: it can distinguish the position of one large city from a neighboring large city. 0 0. 1 degree of latitude in physical distance is 68.94 statute miles or 59.91 nautical miles (110.95 km) -- for a spherical earth assumption. The distance of each degree of latitude is approximately 111 km. While this is adequate for rough locations on a global scale, for detailed work it will be inadequate. deren Differenz bei zwei Punkten in die Einheit Meter. The Earth is not quite a sphere, so you need to get to 6.6 degrees latitude (north or south) before the distances are the same (110.588 km … This tool calculates the distance between two points on the Moon, using the spherical law of cosines, and assumes a spherical Moon of radius 1737.4 km. Latitude … Calculate The Linear Distance Between Sacramento (38.5° N) And Mt. Über den Satz des Pythagoras ist Diff := sqrt( sqr(x2-x1) + sqr(y2-y1) ). A minute is thus 69.44/60 = 1.157 miles, and a second is 1.15/60 = 0.0193 miles, or about 101 feet. deg = km2deg(340) deg = 3.0577 How many degrees would it be if the cities were on Mars? At latitude theta^o N/S, the radius is 6378.1-(theta/90)(21.3) km, nearly. About 111.1 km at the equator, shrinking steadily to zero at the poles. How many kilometers are represented by 1° of latitude? There is not much difference between 4° and 5° and 79° and 80°. one degree of latitude at equator = 110.574 km. How many degrees of arc is that? 1 degree° = 60 arc minutes ' 1 arc minute ' = 60 arc seconds '' 1 arc second '' at equatorial sea level = 1852m/60 = 30.86666667m Ex. I'm sorry to tell you, but that's a difference of 0.67%. 1 degree longitude ~111km at the equator and 0km at the geographical poles - it varies non-linearly according to lattitude. Since one degree (1°) near the equator is equivalent to about 111 km, either moving to south or north poles of both the longitude and the latitude, though slight difference of about 1km. (at N pole, the change is essentially 0. at the equator, use equatorial radius. Latitude, usually denoted by the Greek letter phi (φ) gives the location of a place on Earth (or other planetary body) north or south of the equator. The equatorial radius of the Earth is 6378.1 km.
