SwitchExplanation
Formula: Earth Radii = Kilometers × 0.000156961014. 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.
Kilometers (km): a metric distance unit often used for planetary, orbital, and near-Earth scale reporting.
Earth Radii (R_earth): a planetary scale unit based on Earth's reference radius, useful for comparative astronomy and planetary science.
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 Kilometers to Earth Radii 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 Kilometers to Earth Radii?
Use the mirror Earth Radii to Kilometers route; it applies the inverse relationship for the opposite direction with the same assumptions.
Can I use decimal values for Kilometers to Earth Radii?
Yes. Decimal inputs are supported for Kilometers to Earth Radii, and the mirror direction keeps inverse assumptions aligned.
