To convert Bohr radii to kilometers, multiply the value by 5.29177 × 10⁻¹⁴. To go the other way, multiply kilometers by 18,897,300,000,000 to get Bohr radii.
| Bohr Radii (a₀) | Kilometers (km) |
|---|---|
| 1 a₀ | 5.29177 × 10⁻¹⁴ km |
| 2 a₀ | 1.05835 × 10⁻¹³ km |
| 5 a₀ | 2.64589 × 10⁻¹³ km |
| 10 a₀ | 5.29177 × 10⁻¹³ km |
| 20 a₀ | 1.05835 × 10⁻¹² km |
| 50 a₀ | 2.64589 × 10⁻¹² km |
| 100 a₀ | 5.29177 × 10⁻¹² km |
| 500 a₀ | 2.64589 × 10⁻¹¹ km |
| 1,000 a₀ | 5.29177 × 10⁻¹¹ km |
250 a₀ × 5.29177 × 10⁻¹⁴ = 1.32294 × 10⁻¹¹ km
Try this example →Bohr radius (a₀). The Bohr radius is about 5.29177 × 10⁻¹¹ m, the most probable distance between the nucleus and the electron in a hydrogen atom.
Kilometer (km). A kilometer is 1,000 meters and the standard unit for road distances in most countries, including India.
There are 5.29177 × 10⁻¹⁴ kilometers in one Bohr radius.
Multiply the number of Bohr radii by 5.29177 × 10⁻¹⁴. For example, 10 Bohr radii equal 5.29177 × 10⁻¹³ kilometers.
One kilometer equals 18,897,300,000,000 Bohr radii.
