Straight Line Flight Distance Calculator

This calculator requires the use of Javascript enabled and capable browsers. This script creates a calculated distance result from starting point A to destination point B, determined by latitude and longitude coordinates designated in decimal degrees. Once you enter your decimal degree location for latitude and longitude, enter the N, S, E, and W correct direction (capitalization and spacing is not critical) AFTER the decimal degree entry in the same field box. (If you must use "0" for a latitude , use an "N" for the hemisphere indicator.) Enter the values in decimal degrees. DDD.DDDD E (longitude) and DD.DDDD N (latitude) as examples. Add the directional identifier (N, S, E or W, upper or lower case) with or without a space after the numeric portion of the entry entry. Click on Calculate. Results are given in statute miles, nautical miles and kilometers. This calculation uses the straight line method of distance between two points on the Earth's surface, and should be use for distances of less than 2,000 flight miles, preferably not near the poles. If you need to get that information to a degrees, minutes and seconds format, use the GPS Converter, or for distance information in a slightly different format and with a great circle method of calculation, try our GPS Latitude and Longitude Distance Calculator.

How about a short hypothetical trip from the desert southwest in southern California, Palm Springs, to Santa Catalina Island, off of the coast? The coordinates for the Palm Springs airport are latitude, 33.830N and longitude, 116.5070W. The airport on Santa Catalina island has the coordinates of 33.405N latitude and 118.416W longitude. Those are the defaults for our calculator. Click on Calculate and enjoy the trip!
