What Does FJ Stand For?
FJ stands for Femtojoule
FJ, or Femtojoule, is a unit of energy that is equal to one quintillionth of a joule (10^-15 joules). It is commonly used in fields such as quantum mechanics, photonics, and nanotechnology to quantify extremely small amounts of energy in various scientific and engineering applications. The femtojoule scale is critical for understanding processes that occur at the atomic and subatomic levels.
