Joules and kWh (kilowatt-hour) both are the most common units of energy. These units typically used in certain fields of activity including physics, chemistry, and other industries. Our joules to kilowatt hours calculator works best for both those who are working in these fields of activity and even for students who study energies as Joules and kWh (kilowatt-hour) at school.

An online joules to kWh converter is helps you to convert the value (number) of the Joules into the value of kilowatt-hour (kWh). All you have to add the value of joules into the first field and the converter for energy do the rest for you and even automatically convert joules to kilowatts (j to kWh).

Also, if you require doing manual calculations, here you get the formula that helps you for converting the number of Joules into the number of kilowatt-hour.

Well, first, read on to explore basic definition of joules (j) and kWh (kilowatt-hours)!

Joules (j):

In the International System of Units (SI), Joule is indicated as a unit of work or energy that equal to the work which done by a force of 1 N (Newton) when its point of application moves via a distance of 1 m (meter) in the direction of the force – it is equivalent to 10 7ergs and one watt-second.

Definition of kiloWatt-hour (kWh):

It is said to be as a unit of energy that is equivalent to the energy transferred or expended in one hour by 1 kilowatt of power: approximately 1.34 horsepower-hours.

  • 1 joule (j) is equal to 2.777777777e-7 kilowatt hour (kwh)
  • 1 kilowatt hour (kwh) is equal to 3.6e+6 joules (j)

Joule to Kilowatt Hour Formula:

The formula for joules to kWh is:

kWh = J * 0.000000277777778

How do you convert joule to kilowatt hour?

Convert with:

  • Online j to kwh converter
  • Formula (the below example helps you)

Example of conversions from joules to kWh:

Problem: Convert 890 joules into kWh?


Step 1 (Formula):

  • kWh = J * 0.000000277777778

Step 2 (Put the Values):

  • kWh = 890 * 0.000000277777778

Step 3 (Result):

  • 0.000247222222153 kwh

Means, 890 joules (j) is equal to 0.000247222222153 kilowatt hour (kwh)
