Calories to electronvolts Conversion

1 calories (cal) is equal to 26114473970000000000 electronvolts (eV).

1 cal = 26114473970000000000 eV

1 eV = 0.00000000000000000003829294058 cal

Formula

To convert a energy from calories (cal) to electronvolts (eV), multiply the energy in calories by 26114473970000000000

e_(eV) = e_(cal) × 26114473970000000000

Examples:

Convert 100 calories to electronvolts:

e_(eV) = 100cal × 26114473970000000000 = 2611447397000000000000 eV
