Frequently Asked Questions

How do I convert Joules to Electron-Volts?

Multiply the value in Joules by 6.24220e+18. For instance, 1000 J = 6.24220e+21 eV.

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 Joules to Electron-Volts?

eV = J × 6.24220e+18. This factor relates the two energy units through their definitions in joules.
