⚡ Kilometers to Bohr Radii: the quick answer

1 km = 18,897,300,000,000 a₀ 1 kilometer equals 18,897,300,000,000 Bohr radii

To convert kilometers to Bohr radii, multiply the value by 18,897,300,000,000. To go the other way, multiply Bohr radii by 5.29177 × 10⁻¹⁴ to get kilometers.

↔ Convert Bohr radii to kilometers instead

🧮 Formula

Kilometers to Bohr Radii
a₀ = km × 18,897,300,000,000
Bohr Radii to Kilometers
km = a₀ × 5.29177 × 10⁻¹⁴

Where

  • km = the length in kilometers
  • a₀ = the length in Bohr radii
Every unit here is defined by its length in meters, so the conversion factor is (meters per kilometer) ÷ (meters per Bohr radius).
