About Nanometer (nm) and Astronomical Unit (AU) Units
What is a Nanometer (nm)?
A nanometer is a unit of length equal to one-billionth of a meter:
1 nm = 1 × 10⁻⁹ meters.
Nanometers are commonly used in physics, nanotechnology, and materials science to measure atomic or molecular structures, wavelengths of light, and nanoscale objects.
What is an Astronomical Unit (AU)?
An Astronomical Unit (AU) represents the average distance from Earth to the Sun and is defined as:
1 AU = 149,597,870.7 kilometers = 1.495978707 × 10¹¹ meters.
This unit is essential in astronomy, simplifying the enormous distances between celestial bodies into a standard, comparative measure.
What Does This Converter Do?
This converter transforms Nanometers (nm) — the tiniest units of measurable length — into Astronomical Units (AU), which define the grand scale of the solar system.
By using this tool, you can understand just how small a nanometer truly is compared to the vastness of space — a difference that spans 29 orders of magnitude.
How to Convert Between Nanometers and Astronomical Units
To convert Nanometers (nm) to Astronomical Units (AU):
AU = nm ÷ 1.495978707 × 10²⁰
Or approximately:
1 nm ≈ 6.6846 × 10⁻²¹ AU
That means a single nanometer equals just 0.0000000000000000000066846 AU — highlighting the astonishing difference between atomic and astronomical scales.
