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.
A.u. Of Length
The atomic unit of length, also known as the Bohr radius (a₀), is approximately 5.29 x 10⁻¹¹ meters.
History/Origin
The Bohr radius is named after Niels Bohr, who proposed a model of the atom in 1913 where the electron orbits the nucleus at specific distances. The Bohr radius is the most probable distance between the proton and electron in a hydrogen atom in its ground state.
Current Use
The atomic unit of length is used in atomic physics to simplify calculations and equations.
