Convert attojoule to joule
Please provide values below to convert attojoule [aJ] to joule [J], or Convert joule to attojoule.
1 aJ = 1.0000e-18 J. To convert attojoule to joule, multiply the value by 1.0000e-18; to go the other way, divide by it (1 J = 1.0000e+18 aJ). Both units measure energy and appear in everyday as well as technical calculations, so switching between them quickly is often useful.
Quick Reference
- 1 aJ = 1.0000e-18 J
- 1 J = 1.0000e+18 aJ
- 10 aJ = 1.0000e-17 J
- 100 aJ = 1.0000e-16 J
How to Convert Attojoule to Joule
1 aJ = 1e-18 J
Example: convert 15 aJ to J:
15 aJ = 15 × 1e-18 J = 1.5e-17 J

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.
Joule
The joule (J) is the SI unit of energy, work, and heat, defined as the work done when a force of one newton acts over a distance of one meter.
History/Origin
The joule was named after James Prescott Joule in 1889 to honor his work in energy and thermodynamics. It was adopted as the SI unit of energy in 1948.
Current Use
The joule is widely used in physics, engineering, and everyday contexts to quantify energy, work, and heat in various applications, including electricity, mechanics, and thermodynamics.
Frequently Asked Questions
