You can do the reverse unit conversion from kilometro to astronomical unit, or enter any two units below:
The astronomical unit (AU or au or a.u. or sometimes ua) is a unit of length defined to be exactly equal to 149,597,870,700 metres. Historically, the astronomical unit was conceived as the average Earth-Sun distance (the average of Earth's aphelion and perihelion), before its modern redefinition.
The symbol "ua" is recommended by the Bureau International des Poids et Mesures, but in the United States and other anglophone countries the reverse usage is more common. The International Astronomical Union recommends "au" and international standard ISO 31-1 uses "AU".
The SI prefix "kilo" represents a factor of 103, or in exponential notation, 1E3.
So 1 kilometro = 103 metros.
The definition of a metro is as follows:
El metro es la unidad de longitud del Sistema Internacional de Unidades. Se define como la longitud del trayecto recorrido en el vacío por la luz durante un tiempo de 1/299 792 458 de segundo (unidad de tiempo) (aproximadamente 3,34 ns).
