Convert kilowatt-hour to attojoule
Please provide values below to convert kilowatt-hour [kW*h] to attojoule [aJ], or Convert attojoule to kilowatt-hour.
1 kW*h = 3.6000e+24 aJ. To convert kilowatt-hour to attojoule, multiply the value by 3.6000e+24; to go the other way, divide by it (1 aJ = 2.7778e-25 kW*h). Both units measure energy and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 kW*h = 3.6000e+24 aJ
- 1 aJ = 2.7778e-25 kW*h
- 10 kW*h = 3.6000e+25 aJ
- 100 kW*h = 3.6000e+26 aJ
How to Convert Kilowatt-Hour to Attojoule
1 kW*h = 3.6e+24 aJ
Example: convert 15 kW*h to aJ:
15 kW*h = 15 × 3.6e+24 aJ = 5.4e+25 aJ

Kilowatt-Hour
A kilowatt-hour (kW·h) is a unit of energy equal to the energy transferred or used when a power of one kilowatt is sustained for one hour.
History/Origin
The kilowatt-hour originated in the late 19th century with the development of electrical power systems, becoming a standard unit for measuring electrical energy consumption and billing.
Current Use
It is widely used today in electricity billing, energy consumption monitoring, and in various engineering and scientific applications to quantify electrical energy usage.
Attojoule
An attojoule (aJ) is a unit of energy equal to 10^-18 joules.
History/Origin
The attojoule was introduced as part of the SI prefixes to measure extremely small amounts of energy, particularly in fields like nanotechnology and quantum physics, as the need to quantify very tiny energy scales grew.
Current Use
The attojoule is used in scientific research to measure minute energy quantities, such as in nanotechnology, quantum computing, and molecular biology, where energies involved are extremely small.
