SwitchExplanation
Formula: Lunar Distances = Astronomical Units × 389.1724. 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.
Lunar Distances (LD): a practical astronomy unit based on the mean Earth-Moon distance, often used for near-Earth object 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 Astronomical Units to Lunar Distances 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 Lunar Distances?
Use the mirror Lunar Distances 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 Lunar Distances?
Yes. Decimal inputs are supported for Astronomical Units to Lunar Distances, and the mirror direction keeps inverse assumptions aligned.
