What is a span (cloth)?

A span (cloth) is a traditional length unit based on the distance between the thumb and little finger of an outstretched hand, approximately 9 inches or 22.9 cm.

What does picometer measure?

A picometer is an SI length unit equal to 10⁻¹² meters, used to describe extremely small distances such as atomic bond lengths and crystal lattice spacings.

Why convert span (cloth) to picometers?

To relate traditional textile measurements to precise nanoscale lengths, useful in scientific analysis, textile history, and material science research.
