How to convert electronvolts to British thermal units
There are 6.585141 × 10²¹ electronvolts in one British thermal unit, so divide the number of electronvolts by 6.585141 × 10²¹.
BTU = eV ÷ 6.585141 × 10²¹
1 eV = 1.51857 × 10⁻²² BTU · 1 BTU = 6.585141 × 10²¹ eV
Worked example
To convert 5 electronvolts to British thermal units: 5 eV ÷ 6.585141 × 10²¹ = 7.592852 × 10⁻²² BTU.
