Formula
To convert a energy from British thermal units (BTU) to electronvolts (eV), multiply the energy in British thermal units by 6585140678000000000000
e(eV) = e(BTU) × 6585140678000000000000
Examples:
Convert 100 British thermal units to electronvolts:
e(eV) = 100BTU × 6585140678000000000000 = 658514067800000000000000 eV
