What does one attojoule represent?

One attojoule is an SI unit of energy equal to 10^-18 joules, commonly used to express very tiny energy amounts at the atomic or molecular level.

Is a newton meter the same as a joule?

Yes, a newton meter and a joule are dimensionally equivalent as both represent energy, but in engineering, newton meter can also refer to torque, which is conceptually different.

Why convert attojoules to newton meters?

Converting attojoules to newton meters helps relate extremely small quantum or nanoscale energy values to classical mechanical energy or work units.
