Good to Know About Astronomical Units to Nanometers Conversion
The nanometer defines modern technology (3-nm chips, 100-nm nanoparticles), while the AU defines our place in the solar system. Both are fundamental to modern civilization but at incompatible scales.
Astronomical Units to Nanometers: What You Need to Know
The Earth-Sun distance is about 150 quintillion nanometers. A 3-nm semiconductor chip transistor is 2 x 10-20 AU across. A DNA strand at 2.5 nm is 1.7 x 10-20 AU wide. These numbers demonstrate the 20-order-of-magnitude gap between nanoscale technology and planetary distances.
What is a Astronomical Unit? au
Exactly 149,597,870,700 meters by IAU 2012 definition. Roughly the average distance from the Earth to the Sun. Used for distances within our solar system.

Astronomical Units to Nanometers FAQ
-
One AU contains approximately 1.496 x 1020 nanometers (about 150 quintillion nm). Since 1 AU = 149,597,870,700 m and 1 m = 109 nm, multiply.
-
A nanometer is 6.685 x 10-21 AU. You would need to line up about 150 quintillion nanometer-scale objects to span the Earth-Sun distance.
-
No. Nanotechnology works in nanometers. Astronomy works in AU, light-years, and parsecs. These fields never need to convert between each other's units.
Non-Frequently Asked Questions About Astronomical Units to Nanometers
Questions nobody should ask - but someone did.
-
Human DNA is about 2.5 nm wide. 1 AU is about 1.496 x 1020 nm. So about 60 quintillion DNA widths span the Earth-Sun distance. But a single human cell's DNA uncoiled is about 2 meters long, so just 75 billion uncoiled DNA molecules would reach the Sun.
