What is a span (cloth)?

A span (cloth) is a traditional non-SI unit of length based on the distance between the tip of the thumb and little finger of an outstretched hand, commonly about 9 inches or approximately 22.9 centimeters.

What does a light year measure?

A light year measures the distance light travels in a vacuum in one Julian year, approximately 9.4607 × 10^15 meters, used mainly to express distances in astronomy.

Why convert from span (cloth) to light years?

This conversion helps illustrate the vast difference between human-scale measurements and astronomical distances, often for educational purposes or curiosity.
