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.

Frequently Asked Questions
What is a Joule?
A Joule is a unit of energy in the International System of Units (SI). It measures the amount of energy used when a force of one newton moves an object one meter.
What is a kilowatt-hour (kWh)?
A kilowatt-hour is a unit of energy equal to the energy used by a 1-kilowatt appliance running for one hour. It is commonly used to measure electrical energy consumption.
Why convert Joules to kilowatt-hours?
Converting Joules to kilowatt-hours can help in comparing energy consumption across different units, especially in the context of electrical energy billing and consumption.
What other units are related to energy?
Other units of energy include calories, British thermal units (BTUs), and electronvolts (eV).
How accurate is the conversion?
The conversion formula provided is accurate for converting Joules to kilowatt-hours. It uses the exact conversion factor of 1 J = 2.777778 × 10-7 kWh.
Can I use this calculator for other energy units?
No, this calculator is specifically designed for converting Joules to kilowatt-hours. Other energy units require different formulas.
What is the formula for converting Joules to kilowatt-hours?
The formula is E(kWh) = E(J) / 3,600,000.
Can I convert kilowatt-hours to Joules?
Yes, you can. To convert kWh to Joules, use the formula E(J) = E(kWh) × 3,600,000.
