Questions & answers

Frequently Asked Questions

How is Solar Diameters to Earth Radii calculated?

The factor is derived by reducing both units to meters and applying the fixed planetary or solar radius/diameter reference constants for the route.

How do I reverse Solar Diameters to Earth Radii?

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