Convert petameter to a.u. of length
Please provide values below to convert petameter [Pm] to a.u. of length [a.u., b], or Convert a.u. of length to petameter.
1 Pm = 1.8897e+25 a.u., b. To convert petameter to a.u. of length, multiply the value by 1.8897e+25; to go the other way, divide by it (1 a.u., b = 5.2918e-26 Pm). Both units measure length and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 Pm = 1.8897e+25 a.u., b
- 1 a.u., b = 5.2918e-26 Pm
- 10 Pm = 1.8897e+26 a.u., b

Petameter
A petameter is a unit of length in the metric system equal to 10^15 meters.
History/Origin
The prefix "peta-" for 10^15 was adopted by the CGPM (General Conference on Weights and Measures) in 1975.
Current Use
The petameter is used for measuring distances on a galactic scale, such as the size of the Milky Way galaxy.
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.
