SwitchExplanation
Formula: Astronomical Units = Solar Diameters × 0.009300934522. 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.
Astronomical Units (AU): a standard astronomy distance unit defined exactly as 149,597,870,700 meters, commonly used for Solar System scales.
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 Astronomical Units 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 Solar Diameters to Astronomical Units?
Use the mirror Astronomical Units 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 Astronomical Units?
Yes. Decimal inputs are supported for Solar Diameters to Astronomical Units, and the mirror direction keeps inverse assumptions aligned.
