Span (Cloth)
A span is an obsolete unit of length, typically about 9 inches, based on the distance between the tip of the thumb and the tip of the little finger when the hand is fully extended.
History/Origin
The span has been used as a unit of measurement for thousands of years in many different cultures.
Current Use
The span is no longer a standard unit of measurement.
Planck Length
The Planck length is the smallest possible unit of length in the universe, approximately 1.6 x 10⁻³⁵ meters.
History/Origin
The Planck length is derived from fundamental physical constants and is named after the physicist Max Planck. It is a fundamental unit in the system of Planck units.
Current Use
The Planck length is a theoretical concept used in quantum gravity and cosmology to describe phenomena at the smallest scales of the universe.
