Convert astronomical units to ångströms
1 au = 1495978707000000000000 Å — exactly. Both units are defined against the SI, so this factor is a fraction, not an approximation.
How to convert astronomical units to ångströms
Multiply the number of astronomical units by 1495978707000000000000 to get ångströms.
The exact factor is 1495978707000000000000 .
Astronomical unit: Fixed at exactly 149 597 870 700 m by the IAU in 2012.
Ångström: Convenient for atomic radii and X-ray wavelengths.
