SwitchExplanation
Formula: Earth Radii = Light-Years × 1,484,965,846. Why: larger astronomy distance scales such as light-years and parsecs are normalized through meters using fixed reference relationships, then restated in the target unit.
Light-Years (ly): the distance light travels in one Julian year in vacuum, widely used for interstellar distances.
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 planetary, stellar, and standard distance scales so astronomy references stay on the intended unit system.
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-Years to Earth Radii calculated?
The factor is derived by reducing both units to meters and applying the fixed deep-space reference constants for light-years and parsec-based scales.
How do I reverse Light-Years to Earth Radii?
Use the mirror Earth Radii to Light-Years route; it applies the inverse relationship for the opposite direction with the same assumptions.
Can I use decimal values for Light-Years to Earth Radii?
Yes. Decimal inputs are supported for Light-Years to Earth Radii, and the mirror direction keeps inverse assumptions aligned.
