SwitchExplanation
Formula: Earth Diameters = Solar Diameters × 109.197777. 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 Diameters (D_earth): a comparative planetary size-distance unit based on Earth's mean diameter.
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 Diameters 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 Diameters?
Use the mirror Earth Diameters 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 Diameters?
Yes. Decimal inputs are supported for Solar Diameters to Earth Diameters, and the mirror direction keeps inverse assumptions aligned.
