What is the Earth's equatorial radius?

It is the straight-line distance from Earth's center to the equator along the equatorial plane, standardized as 6,378.137 kilometers.

What does a gigameter represent?

A gigameter is an SI unit of length equal to one billion meters or one million kilometers, commonly used for expressing astronomical distances.

Why convert Earth's equatorial radius to gigameters?

This conversion helps express Earth's size relative to vast cosmic distances, integrating geodetic data with astronomy and planetary science.
