Questions & answers

Frequently Asked Questions

How is Earth Diameters to Light-Seconds 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 Earth Diameters to Light-Seconds?

Use the mirror Light-Seconds to Earth Diameters route; it applies the inverse relationship for the opposite direction with the same assumptions.
