Convert Latitudes and Longitudes into Distance

Here, an angular measurement on Earth can be converted into kilometers and miles. A point's location on Earth is expressed using two angular coordinates, the first is latitude, the second is longitude. Latitude represents the angular distance from the Equator, while longitude represents the angular distance from the Prime Meridian passing through Greenwich, near London, England. This tool allows for the calculation of distances along lines of latitude (north or south) and longitude (east or west). Calculating distance involving both directions is more complicated, for this see distance between two points.

Latitudes

On Earth, lines of latitude are spaced almost equidistantly, approximately 111 kilometers per degree. The distance is slightly less at the equator (110.574 km) than at the poles (111.694 km). Therefore, specifying the latitude is not strictly necessary here. Enter an angular value in degrees, and/or arcminutes, and/or arcseconds to calculate the corresponding distance to the north or south.

Longitudes

Lines of longitude are furthest apart at the equator. The distance between them decreases as latitude increases, reaching zero at the poles. At the equator, the distance is 111.319 km, roughly the same as the distance between lines of latitude, whereas at the 50th parallel, it is approximately 71.7 km. Therefore, specifying the latitude is essential here. Enter an angular value in degrees, and/or arcminutes, and/or arcseconds to calculate the corresponding distance in an east-west direction.

The distance in degrees for latitude is calculated using the Earth's radius of meridian curvature. This value accounts for the Earth's slight oblateness and varies slightly depending on the latitude. The distance is determined by the formula: distance = angle × radius of meridian curvature.
For the distance between lines of longitude, the radius of the parallel of latitude (see rotational radius) at the specific latitude is used. This radius decreases as the distance from the equator increases. The distance is determined by the formula: distance = angle × radius of the parallel.
