You can do the reverse unit conversion from astronomical unit to zettameter, or enter any two units below:

zettameter to millimicron

zettameter to petameter

zettameter to hectometer

zettameter to nanon

zettameter to click

The SI prefix "zetta" represents a factor of
10^{21}, or in exponential notation, 1E21.

So 1 zettametre = 10^{21} metre.

The astronomical unit (AU or au or a.u. or sometimes ua) is a unit of length. It is approximately equal to the mean distance between the Earth and Sun. The currently accepted value of the AU is 149 597 870 691 ± 30 metres (about 150 million kilometres or 93 million miles).

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".
