Convert Bohr radius to span (cloth)
Please provide values below to convert Bohr radius [a.u.] to span (cloth) [span], or Convert span (cloth) to Bohr radius.
1 a.u. = 2.3149e-10 span. To convert Bohr radius to span (cloth), multiply the value by 2.3149e-10; to go the other way, divide by it (1 span = 4319913920.89 a.u.). Both units measure length and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 a.u. = 2.3149e-10 span
- 1 span = 4319913920.89 a.u.
- 10 a.u. = 2.31486094008e-09 span
- 100 a.u. = 2.31486094008e-08 span
How to Convert Bohr Radius to Span (Cloth)
1 a.u. = 2.31486094008311e-10 span
Example: convert 15 a.u. to span:
15 a.u. = 15 × 2.31486094008311e-10 span = 3.47229141012467e-09 span

Bohr Radius
The Bohr radius is the most probable distance between the proton and the electron in a hydrogen atom in its ground state, 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. It is the atomic unit of length.
Current Use
The Bohr radius is a fundamental constant in atomic physics and is used to simplify calculations and equations.
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.
