Explanation

This is the reverse side of the AU-to-solar-radii conversion. It answers the astronomy distance question directly: 1 solar radius is about 0.004650467261 astronomical units on this page.

That is useful when you want to express stellar size in orbital-distance units for comparison or quick reference work. The page uses the same fixed meter-based constants as the mirror page, only reversed, so both directions stay aligned.

Method & Reference

Method basis: exact conversion formula shown in Snapshot.
Applied factor: 1 Solar Radius = 0.004650467261 Astronomical Units.
Consistency rule: calculator output and table values use the same constants and rounding policy.

Questions & answers

Frequently Asked Questions

Is this the reverse of the AU to solar radii page?

Yes. This page uses the same fixed astronomy distance constants as the mirror page, only reversed to estimate astronomical units from solar radii.

Why is 1 solar radius such a small fraction of an AU?

Because an astronomical unit is much larger than the radius of the Sun, so one solar radius is only a small fraction of 1 AU.
