API, OpenAPI and WebMCP documentation

Explanation

Earth Diameters convert into solar radii using fixed astronomy size constants anchored to meters. Formula: R_sun = D_earth × 0.0183153911169. That keeps the snapshot, calculator, table, and mirror page aligned on one constant basis.

It is useful for comparing planetary, stellar, and orbital-scale size references without switching between inconsistent reference tables.

Method & Reference

Method basis: exact conversion formula shown in Snapshot.
Applied factor: 1 Earth Diameter = 0.018315 Solar Radii.
Consistency rule: calculator output and table values use the same constants and rounding policy.

Questions & answers

Frequently Asked Questions

What is 1 earth diameter in solar radii?

1 Earth Diameter equals 0.018315 Solar Radii on this page.

Does this Earth Diameters to Solar Radii page use fixed solar reference constants?

Yes. Where solar radii or diameters appear, this page uses fixed solar reference constants normalized through meters before applying the target unit.

When would I convert earth diameters to solar radii?

This route is useful when translating between stellar size references and other astronomy scales so star-size comparisons stay on the intended unit basis.

How do I reverse Earth Diameters to Solar Radii?

Use the mirror Solar Radii to Earth Diameters route; it reverses the same astronomy size constants without changing the underlying assumptions.
