Calorie (cal)
The calorie is used for heat energy and often appears in nutrition and chemistry.
History: the calorie originated in heat science as a quantity of heat related to warming water.
Quickly convert calories to electronvolts without lookup tables or manual math.
This page is focused on converting calories to electronvolts. Type a number into the first field and the result appears immediately in the second field.
Example: 1 cal = 2.6114473968E+19 eV. Conversion formula: result = value × 4.184 / 1.602176634E-19.
Use this converter for everyday calculations, study notes, engineering checks, and quick value verification without installing a separate app.
