5 Kilowatt-Hours to Joules

18000000 J

5 kWh = 18000000 J

5 kWh = 18000000 J

To convert kilowatt-hours to joules, multiply the value by the conversion factor:

1 kWh = 3600000 J
5 kWh × 3600000 = 18000000 J

Reverse: 18000000 joules = 5 kilowatt-hours

kilowatt-hours (kWh) joules (J)
5 18000000
1 3600000
10 36000000
50 180000000
100 360000000

kilowatt-hours (kWh)

The kilowatt-hour (kWh) is the unit of energy used to bill electricity. It is not a unit of power (kilowatts), but of energy: it is 1,000 watts of power sustained for one hour. One kWh equals exactly 3.6 million Joules. It was popularized by the electric utility industry as a unit easy for consumers to understand.

Running a 1,000W microwave for one hour uses 1 kWh.

Commonly used in: Electric bills, Electric vehicle batteries, Solar panel output, Home energy audits, Power plant generation.

joules (J)

The Joule (J) is the standard unit of energy in the International System of Units (SI). It is named after James Prescott Joule, who proved that heat is a form of energy. One Joule is the work done by a force of one Newton moving an object one meter. It is a small unit: lifting a small apple one meter takes about 1 Joule.

The energy of a heartbeat is roughly 1 Joule.

Commonly used in: Scientific research, Physics education, Electronics ratings, Kinetic energy calculations, Work done.
