What does Earth's equatorial radius represent?

It is the straight-line distance from Earth's center to the equator along the equatorial plane according to the standard WGS84 reference ellipsoid.

Why would I convert Earth's radius to picometers?

This conversion helps relate very large Earth-scale measurements to atomic and subnanometre scales used in physics and chemistry.

Is this conversion useful for everyday measurements?

No, due to the huge conversion factor, it's mostly intended for theoretical or specialized scientific contexts.
