Convert Bohr radius to petameter
Please provide values below to convert Bohr radius [a.u.] to petameter [Pm], or Convert petameter to Bohr radius.
1 a.u. = 5.2918e-26 Pm. To convert Bohr radius to petameter, multiply the value by 5.2918e-26; to go the other way, divide by it (1 Pm = 1.8897e+25 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. = 5.2918e-26 Pm
- 1 Pm = 1.8897e+25 a.u.
- 10 a.u. = 5.2918e-25 Pm
- 100 a.u. = 5.2918e-24 Pm
How to Convert Bohr Radius to Petameter
1 a.u. = 5.29177210903e-26 Pm
Example: convert 15 a.u. to Pm:
15 a.u. = 15 × 5.29177210903e-26 Pm = 7.937658163545e-25 Pm

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.
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
