Convert a.u. of length to Roman actus
Please provide values below to convert a.u. of length [a.u., b] to Roman actus [actus], or Convert Roman actus to a.u. of length.
1 a.u., b = 1.4915e-12 actus. To convert a.u. of length to Roman actus, multiply the value by 1.4915e-12; to go the other way, divide by it (1 actus = 670450592255 a.u., b). Both units measure length and appear in everyday as well as technical calculations, so switching between them quickly is often useful.

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.
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.
