What is Earth's equatorial radius used for?

It is used for defining reference ellipsoids, map projections, satellite orbit calculations, ground track analysis, and coordinate conversions in fields like geodesy, cartography, and aerospace engineering.

How is a centimeter defined in this conversion?

A centimeter is a metric unit of length equal to one hundredth of a meter, commonly used for measuring small to moderate linear distances in everyday and scientific contexts.

Why convert Earth's equatorial radius to centimeters?

Converting to centimeters allows expression of very large geodetic measurements in smaller, more precise units useful for technical calculations, detailed mapping, and scientific documentation.
