Millimeters to Bohr Radii Converter

⚡ Millimeters to Bohr Radii: the quick answer

1 mm = 18,897,300 a₀ 1 millimeter equals 18,897,300 Bohr radii

To convert millimeters to Bohr radii, multiply the value by 18,897,300. To go the other way, multiply Bohr radii by 5.29177 × 10⁻⁸ to get millimeters.

↔ Convert Bohr radii to millimeters instead

🧮 Formula

Millimeters to Bohr Radii

a₀ = mm × 18,897,300

Bohr Radii to Millimeters

mm = a₀ × 5.29177 × 10⁻⁸

Where

mm = the length in millimeters
a₀ = the length in Bohr radii

Every unit here is defined by its length in meters, so the conversion factor is (meters per millimeter) ÷ (meters per Bohr radius).
