Classical electron radii to Kilometers Converter

1 classical electron radius (rₑ) equals 2.8179403 × 10-18 kilometers (km).

1 classical electron radius = 2.8179403 × 10-18 kilometers

How to convert classical electron radii to kilometers

km = rₑ ÷ 3.5486912 × 1017

To convert classical electron radii to kilometers, divide the number of classical electron radii by 3.5486912 × 1017.

Example: 1 rₑ to km

  1. Start with the value in classical electron radii: 1 rₑ.
  2. Divide by 3.5486912 × 1017: 1 ÷ 3.5486912 × 1017 = 2.8179403 × 10-18.
  3. Result: 1 classical electron radius = 2.8179403 × 10-18 kilometers.

Going the other way, 1 kilometer = 3.5486912 × 1017 classical electron radii, so to convert kilometers back to classical electron radii you multiply by the same number. See kilometers to classical electron radii.
