SwitchExplanation
Formula: Earth Radii = Light-Seconds × 47.055728. 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.
Light-Seconds (ls): the distance light travels in one second in vacuum, useful for short astronomical communication and orbital scales.
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 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 Light-Seconds to Earth Radii 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 Light-Seconds to Earth Radii?
Use the mirror Earth Radii to Light-Seconds route; it applies the inverse relationship for the opposite direction with the same assumptions.
Can I use decimal values for Light-Seconds to Earth Radii?
Yes. Decimal inputs are supported for Light-Seconds to Earth Radii, and the mirror direction keeps inverse assumptions aligned.
