Convert Attojoule to Joule
Attojoule
The attojoule (aJ) is a unit of energy in the International System of Units (SI). It is equal to one quintillionth of a joule (0.000000000000000001 J). The attojoule is commonly used to measure extremely small amounts of energy, such as the energy content of individual photons.
The attojoule is derived from the joule, which is named after James Prescott Joule, an English physicist. The prefix 'atto-' signifies a factor of one quintillionth, making the attojoule equal to one quintillionth of a joule.
Joule
The joule (J) is the SI unit of energy, work, and heat, defined as the amount of energy transferred when a force of one newton acts over a distance of one meter. It is mathematically expressed as 1 J = 1 N·m = 1 kg·m²/s², where N is newton, kg is kilogram, m is meter, and s is second. The joule is commonly used to measure energy in various forms, including mechanical, electrical, and thermal energy.
The joule is named after James Prescott Joule, an English physicist who is best known for his work on the relationship between heat and mechanical work. His experiments in the 19th century demonstrated that mechanical energy could be converted into heat, contributing to the formulation of the law of conservation of energy. His work laid the foundation for modern thermodynamics, highlighting that energy is conserved and can be transformed but not created or destroyed.
