Electronvolts to British thermal units Converter

1 electronvolt (eV) equals 1.5185704 × 10-22 British thermal units (BTU).

Quick answer

  • 1 electronvolt = 1.5185704 × 10-22 British thermal units
  • 1 British thermal unit = 6.5851407 × 1021 electronvolts
  • Formula: BTU = eV ÷ 6.5851407 × 1021

1 electronvolt = 1.5185704 × 10-22 British thermal units

How to convert electronvolts to British thermal units

BTU = eV ÷ 6.5851407 × 1021

To convert electronvolts to British thermal units, divide the number of electronvolts by 6.5851407 × 1021.

Example: 18 eV to BTU

  1. Start with the value in electronvolts: 18 eV.
  2. Divide by 6.5851407 × 1021: 18 ÷ 6.5851407 × 1021 = 2.7334268 × 10-21.
  3. Result: 18 electronvolts = 2.7334268 × 10-21 British thermal units.

Going the other way, 1 British thermal unit = 6.5851407 × 1021 electronvolts, so to convert British thermal units back to electronvolts you multiply by the same number. See British thermal units to electronvolts.
