API, OpenAPI and WebMCP documentation

Explanation

This page answers the astronomy distance comparison directly: 1 astronomical unit is about 215.032156 solar radii on this page. That makes it useful when you want to compare orbital-scale distance to the size of the Sun using one fixed meter-based reference model.

This is useful for stellar system scale comparisons, orbital geometry references, and astronomy notes where AU and solar radii are both used.

Method & Reference

Method basis: exact conversion formula shown in Snapshot.
Applied factor: 1 Astronomical Unit = 215.032156 Solar Radii.
Consistency rule: calculator output and table values use the same constants and rounding policy.
