What is a petameter used for?

A petameter is an SI unit of length equal to 10^15 metres, used for expressing very large distances such as those between nearby stars and large interstellar structures.

What does a span (cloth) measure?

A span (cloth) is a traditional, non-SI unit representing the distance from the tip of the thumb to the tip of the little finger of an outstretched hand, commonly about 9 inches or 22.9 cm.

Why convert petameters to spans (cloth)?

This conversion helps relate extremely large astronomical distances to traditional small-scale units for comparative, cultural, or educational purposes.
