SwitchExplanation
Formula: Kilometers = Solar Diameters × 1,391,400. 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.
Kilometers (km): a metric distance unit often used for planetary, orbital, and near-Earth scale reporting.
This route is useful when translating everyday metric or imperial distances into astronomy reference scales, or when expressing astronomy scales in more familiar distance 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 Kilometers 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 Kilometers?
Use the mirror Kilometers 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 Kilometers?
Yes. Decimal inputs are supported for Solar Diameters to Kilometers, and the mirror direction keeps inverse assumptions aligned.
