Hi-
Can you calculate mileage between two cities using the "Geography" tool in the data types section in the data ribbon? I would like to create a mileage driving chart for about 20 cities.
Thanks!

in B2 is the latitude of location 1 and in B3 the longitude
in B5 is the latitude of location 2 and in B6 the longitude
each degree - decimal
in C2 stands: = B2 * PI () / 180
copy to C6
The distance in km is:
= TEXT (ARCCOS (SIN (C2) * SIN (C5) + COS (C2) * COS (C5) * COS (C6-C3)) * 6378,137, "#. ## 0,0") & "km "
If you don't know how to convert to decimal:
in F1 the hours / in G1 the minutes / in H1 the seconds
= F1 + G1 / 60 + H1 / 3600
Enclosed a calculation file
Great circle navigation = distance calculations on the earth's surface:
Got this from the Internet, don't know where, but in my notes there is this file from a Mr. Klaus Kühnlein who is/or was the Pope in this area in German-speaking countries.
It's really a great job...WoW!
Hope I could help you with this information.

Sample is here LAMBDA Examples: Distance between two cities - Microsoft Tech Community , you may ignore LAMBDA if it is not in your version of Excel.

Do not forget to convert the angles to radians before calculating sines or cosines. Also, it is unlikely that the curvature of the Earth is going to affect the distances you drive that much, the deviations from the straight line route required to follow the highway are far more significant.
