How to convert British thermal units to electronvolts
One British thermal unit equals 6.585141 × 10²¹ electronvolts, so multiply the number of British thermal units by 6.585141 × 10²¹.
eV = BTU × 6.585141 × 10²¹
1 BTU = 6.585141 × 10²¹ eV · 1 eV = 1.51857 × 10⁻²² BTU
Worked example
To convert 5 British thermal units to electronvolts: 5 BTU × 6.585141 × 10²¹ = 3.29257 × 10²² eV.
