Schwarzschild radius (AU) to solar masses
Type a value in AU to get it in M☉ instantly.
4,300,508M☉
That's about the same as Sagittarius A*. As a black hole its event horizon would be 12,700,000 km in radius.
Convert the other way: M☉ to AU
What it means
How massive is that?
Non-rotating (Schwarzschild) black hole. Spinning black holes have a smaller event horizon, down to half for maximum spin.
The math
How to convert AU to M☉
To convert Schwarzschild radius (AU) to solar masses, multiply by 50,653,800.
Example: 0.0849 AU × 50,653,800 = 4,300,510 M☉.
In the other direction, 1 M☉ = 1.974×10⁻⁸ AU.
