Convert nanometer to astronomical unit
Please provide values below to convert nanometer [nm] to astronomical unit [AU, UA], or Convert astronomical unit to nanometer.
1 nm = 6.6846e-21 AU, UA. To convert nanometer to astronomical unit, multiply the value by 6.6846e-21; to go the other way, divide by it (1 AU, UA = 1.4960e+20 nm). Both units measure length and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 nm = 6.6846e-21 AU, UA
- 1 AU, UA = 1.4960e+20 nm
- 10 nm = 6.6846e-20 AU, UA
- 100 nm = 6.6846e-19 AU, UA
How to Convert Nanometer to Astronomical Unit
1 nm = 6.68458712226845e-21 AU, UA
Example: convert 15 nm to AU, UA:
15 nm = 15 × 6.68458712226845e-21 AU, UA = 1.00268806834027e-19 AU, UA

Nanometer
A nanometer is a unit of length in the metric system, equal to one billionth of a meter.
History/Origin
The term “nanometer” gained prominence in the late 20th century with the advent of nanotechnology and the development of microscopes capable of observing objects at that scale.
Current Use
The nanometer is commonly used to express dimensions on an atomic and molecular scale. It is used to specify the wavelength of electromagnetic radiation near the visible part of the spectrum and in the field of nanotechnology.
Astronomical Unit
The astronomical unit is a unit of length, now defined as exactly 149,597,870,700 meters. It is approximately the average distance between the Earth and the Sun.
History/Origin
Historically, the astronomical unit was the mean Earth-Sun distance. In 2012, the International Astronomical Union (IAU) redefined it as a fixed constant.
Current Use
The astronomical unit is used primarily for measuring distances within the Solar System or around other stars.
