SwitchExplanation
Formula: Earth Radii = Solar Diameters × 218.395555. 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.
Solar Diameters (D_sun): a stellar comparison unit based on the Sun's diameter, useful for scale illustrations.
Earth Radii (R_earth): a planetary scale unit based on Earth's reference radius, useful for comparative astronomy and planetary science.
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 Solar Diameters to Earth 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 Solar Diameters to Earth Radii?
Use the mirror Earth Radii to Solar Diameters route; it applies the inverse relationship for the opposite direction with the same assumptions.
Can I use decimal values for Solar Diameters to Earth Radii?
Yes. Decimal inputs are supported for Solar Diameters to Earth Radii, and the mirror direction keeps inverse assumptions aligned.
