SwitchExplanation
Formula: Earth Diameters = Astronomical Units × 11,740.517. 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.
Astronomical Units (AU): a standard astronomy distance unit defined exactly as 149,597,870,700 meters, commonly used for Solar System scales.
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 Astronomical Units to Earth Diameters calculated?
The factor is derived by reducing both units to meters and applying the fixed astronomy reference constants for AU, light-seconds, or lunar-distance scales.
How do I reverse Astronomical Units to Earth Diameters?
Use the mirror Earth Diameters to Astronomical Units route; it applies the inverse relationship for the opposite direction with the same assumptions.
Can I use decimal values for Astronomical Units to Earth Diameters?
Yes. Decimal inputs are supported for Astronomical Units to Earth Diameters, and the mirror direction keeps inverse assumptions aligned.
