SwitchExplanation
Formula: Solar Radii = Earth Diameters × 0.018315391. Why: AU, lunar distance, and planetary radius or diameter units are tied to fixed astronomy reference constants, so the route moves through one meter-based normalization path.
Earth Diameters (D_earth): a comparative planetary size-distance unit based on Earth's mean diameter.
Solar Radii (R_sun): a stellar scale unit based on the Sun's reference radius, common in astronomy comparisons.
This route is useful when comparing Solar System and planetary-scale distances using AU, lunar-distance, and Earth or Solar reference units.
This conversion is purely multiplicative because both units reduce through meters using fixed astronomical or geometric reference constants with no offset.

Frequently Asked Questions
How is Earth Diameters to Solar Radii calculated?
The factor is derived by reducing both units to meters and applying the fixed planetary or solar radius/diameter reference constants for the route.
How do I reverse Earth Diameters to Solar Radii?
Use the mirror Solar Radii to Earth Diameters route; it applies the inverse relationship for the opposite direction with the same assumptions.
Can I use decimal values for Earth Diameters to Solar Radii?
Yes. Decimal inputs are supported for Earth Diameters to Solar Radii, and the mirror direction keeps inverse assumptions aligned.
