Convert Bohr radius to Roman actus
Please provide values below to convert Bohr radius [a.u.] to Roman actus [actus], or Convert Roman actus to Bohr radius.
1 a.u. = 1.4915e-12 actus. To convert Bohr radius to Roman actus, multiply the value by 1.4915e-12; to go the other way, divide by it (1 actus = 670450640523 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. = 1.4915e-12 actus
- 1 actus = 670450640523 a.u.
- 10 a.u. = 1.4915e-11 actus
- 100 a.u. = 1.4915e-10 actus
How to Convert Bohr Radius to Roman Actus
1 a.u. = 1.4915341108783e-12 actus
Example: convert 15 a.u. to actus:
15 a.u. = 15 × 1.4915341108783e-12 actus = 2.23730116631744e-11 actus

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.
Roman Actus
The Roman actus was a unit of length equal to 120 Roman feet, about 35.5 meters.
History/Origin
The actus was a standard unit of land measurement in the Roman Empire.
Current Use
The Roman actus is an obsolete unit of measurement.
