Questions & answers

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.
