What is the Earth's equatorial radius?

It is the straight-line distance from the Earth's center to the equator measured along the equatorial plane, defined as 6,378.137 kilometers in the WGS84 reference ellipsoid.

Why use terameters for expressing Earth's dimensions?

Terameters are suited for very large distances, enabling easier comparison with planetary and interplanetary scales in astronomy and geodesy.

Can I use this conversion for everyday measurements?

No, the conversion is mainly conceptual and better suited for scientific and astronomical contexts rather than everyday use.
