Frequently Asked Questions

How do I convert Electron-Volts to Joules?

Multiply the value in Electron-Volts by 1.60200e-19. For instance, 1000 eV = 1.60200e-16 J.

What is the difference between calories and kilocalories?

1 kilocalorie (kcal) = 1000 calories (cal). Food labels use "Calories" (capital C) to mean kilocalories. So a 200-Calorie snack is actually 200,000 small calories or 200 kcal.

What is the formula for Electron-Volts to Joules?

J = eV × 1.60200e-19. This factor relates the two energy units through their definitions in joules.
