## Joules to kWh Calculator

The Joules to kWh Calculator helps you convert energy measured in Joules to kilowatt-hours. This is useful for understanding energy consumption or comparing different energy measurements. The formula used for the conversion is:

**1 Joule = 2.777778 × 10 ^{-7} kilowatt-hours**

So, the energy in kilowatt-hours (kWh) can be calculated by dividing the energy in Joules (J) by 3,600,000:

**E(kWh) = E(J) / 3,600,000**

To use the Joules to kWh Calculator, enter the amount of energy in Joules into the input box and click the "Convert" button. The result will be displayed below in kilowatt-hours.
