The Conversion Formula
To convert kilowatt-hours to joules, multiply the value by the conversion factor: 1 kWh = 3600000 J. For a worked example, suppose you need to convert 25 kWh to joules: 25 × 3600000 = 90000000 J. To convert in the opposite direction, divide by 3600000, or equivalently multiply by 2.7778e-7.
About kilowatt-hours
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. kilowatt-hours are commonly used in Electric bills, Electric vehicle batteries, Solar panel output, and Home energy audits, Power plant generation.
Running a 1,000W microwave for one hour uses 1 kWh.
About joules
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. joules are commonly used in Scientific research, Physics education, Electronics ratings, and Kinetic energy calculations, Work done.
The energy of a heartbeat is roughly 1 Joule.
