What is a petameter used for?

A petameter is an SI unit of length for very large distances, commonly used to express distances larger than the Solar System but less than typical interstellar scales.

Why convert petameters to Earth's equatorial radius?

Converting petameters to Earth's equatorial radius helps relate immense astronomical distances to a tangible Earth-based reference, aiding understanding in astronomy and geodesy.

Is the Earth's equatorial radius a fixed value?

Yes, the Earth's equatorial radius is a defined constant in geodesy, representing the distance from Earth's center to the equator according to the WGS84 standard.
