Calculate the distance in kilometers per degree of longitude or latitude for any location

Updated 22 Sep 2022

This function calculates the distance in kilometers per degree of longitude or latitude for any location. This quantity can be used as the conversion factor to convert between distances in kilometers and distances in degrees of longitude or latitude for any location of interest.
INPUT
phi = degrees of latitude at the location of interest (-90 to 90 deg N)
OUTPUT
dlon = distance in kilometers per degree of longitute at phi
dlat = distance in kilometers per degree of latitute at phi
example use:
>> phi = [0 15 30 45 60 75 90]';
>> [dlon_km dlat_km] = kmperdeg(phi)
phi =
