Convert a.u. of length to petameter
Please provide values below to convert a.u. of length [a.u., b] to petameter [Pm], or Convert petameter to a.u. of length.
1 a.u., b = 5.2918e-26 Pm. To convert a.u. of length to petameter, multiply the value by 5.2918e-26; to go the other way, divide by it (1 Pm = 1.8897e+25 a.u., b). 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., b = 5.2918e-26 Pm
- 1 Pm = 1.8897e+25 a.u., b
- 10 a.u., b = 5.2918e-25 Pm
- 100 a.u., b = 5.2918e-24 Pm
How to Convert A.u. Of Length to Petameter
1 a.u., b = 5.29177249e-26 Pm
Example: convert 15 a.u., b to Pm:
15 a.u., b = 15 × 5.29177249e-26 Pm = 7.937658735e-25 Pm

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.
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.
Frequently Asked Questions
What is 1 a.u. of length in petameter?
1 a.u. of length (a.u., b) = 5.2918e-26 petameter (Pm).
How do you convert a.u. of length to petameter?
