About kilowatt-hours and kilojoules
The Conversion Formula
To convert kilowatt-hours to kilojoules, multiply the value by the conversion factor: 1 kWh = 3600 kJ. For a worked example, suppose you need to convert 25 kWh to kilojoules: 25 × 3600 = 90000 kJ. To convert in the opposite direction, divide by 3600, or equivalently multiply by 0.000277778.
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 kilojoules
The kilojoule (kJ) is the standard unit for food energy in most of the world (Australia, Europe, etc.), replacing the Calorie. One food Calorie (kcal) is approximately 4.2 kJ. It provides a more precise measure of energy intake than the large Calorie. kilojoules are commonly used in Food labels (Global), Exercise machines, Diet planning, and Thermodynamics, Metabolic rate tracking.
A slice of bread has about 300-400 kJ.
When Would You Convert kilowatt-hours to kilojoules?
Converting between kilowatt-hours and kilojoules is one of the most common energy conversions. You might need this conversion when working with international specifications, following instructions written for a different measurement system, or comparing values across different standards. Having the conversion factor (1 kWh = 3600 kJ) memorized or bookmarked can save time in professional and everyday contexts alike.
