Calculate distance between 2 geographical points (great-circle distance):

[VAR] * ACOS
(
SIN( RADIANS([Origin-Latitude]) ) * SIN( RADIANS([Destination-Latitude]) ) +
COS( RADIANS([Origin-Latitude]) ) * COS( RADIANS([Destination-Latitude]) ) *
COS( RADIANS([Destination-Longitude]) – RADIANS([Origin-Longitude]) )
)

[VAR]= 3959 for miles
[VAR]= 6371 for kilometers
