¿Cuál es la distancia en KM entre el centroide de un municipio y otro?

Distancia entre los municipios 'Mexicali' y 'Ensenada':

SELECT ST_Distance(ST_Centroid(a.the_geom_webmercator), ST_Centroid(b.the_geom_webmercator)) / 1000
FROM los_municipios a, los_municipios b
WHERE a.nombre='Mexicali' AND b.nombre='Ensenada'
