Questions & answers

Frequently Asked Questions

How is Astronomical Units 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 Astronomical Units to Earth Radii?

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