Questions & answers

Frequently Asked Questions

How is Earth Radii to Astronomical Units 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 Radii to Astronomical Units?

Use the mirror Astronomical Units to Earth Radii route; it applies the inverse relationship for the opposite direction with the same assumptions.
