    Considering the speed of light is approx. 300,000  Km per second ,(actual 299,792.458 km per second), then 

    1 light second  is approx..                        300,000  Km

    1 light minute  is approx .                         300,000 x 60  Km

    1 light hour     is approx.                          300,000 x 60 x 60 Km

    1 light day      is approx.                          300,000 x 60 x 60 x 24 Km

    1 light year    is approx.                           300,000 x 60 x 60 x 24 x 365  km. 

    I have read that some distant galaxies are at least 1,000  light years  across.

    Therefore  that distance would be approx.: 1,066,530,000,000,000   km. 

    or One thousand and sixty six trillion, five hundred and thirty billion   km. 

    Just interesting. Time on my hands …...
