      Relation Between Nanometer (nm) and Astronomical Unit (au)

      Let me explain to you about the relation between Nanometer nm and Astronomical Unit (au) first before moving to the conversion process. Because it’s essential to grasp what these units represent.

      What is Nanometer (nm)?

      A nanometer is a unit of length equal to 10−9 meters. Nanometer (nm) is a unit of length measurement which is commonly used in Astronomy. Used in nanotechnology, optics, and biology. Describes wavelengths of light and nanoscale structures. Highlights the scale of molecules and atomic dimensions..

      What is Astronomical Unit (au)?

      Nanometer (nm) is another unit of length measurement that is used in Astronomy. An astronomical unit (AU) is the average distance between the Earth and the Sun, approximately 149.6 million kilometers.. Used in nanotechnology, optics, and biology. Describes wavelengths of light and nanoscale structures. Highlights the scale of molecules and atomic dimensions..

      How to Convert Astronomical Unit (au)?

      The conversion between Nanometer (nm) and Astronomical Unit (au) follows a simple formula:

      Nanometer = Nanometer × 6.684587122268446e-21

      Where, 6.684587122268446e-21 is the value that allows you to convert between Nanometer (nm) and Astronomical Unit (au).

      So,

      1 Astronomical Unit = 6.684587122268446e-21 Nanometer

      And, 1 Nanometer = 1/6.684587122268446e-21 Astronomical Unit
