    Actually every 463 meters.

    40 075km is circumference of Earth. There are 24x60x60 seconds in a day.

    40 075×1 000÷(24×60 ×60) =~ 463.8

      Wouldn’t it depend on latitude? It would be much less than 463 metres at the latitudes of Europe

        Yes, distance of 1" on equator (463.8 m) × cosine of latitude longitude. This means approximately 350 m in Rome, 285,6 m in Berlin and 232 m in Helsinki. In reality a bit less, as I didn’t take the ellipsoid shape of the globe into account.
