Is 1 Newton meter exactly equal to 1 Joule?

Yes, 1 Newton meter is dimensionally equal to 1 Joule as it represents energy transferred when a force acts through a displacement.

What is an attojoule used for?

Attojoule is used to express extremely small energy amounts such as those relevant to single photons, nanoscale devices, and molecular processes.

Can the newton meter unit be used to measure torque?

Yes, in engineering contexts newton meter is commonly used to express torque; however, torque and energy are conceptually distinct even though they share the same unit.

Key Terminology

Newton meter [N*m]: A unit of energy equal to one joule, representing work done when a force of one newton acts through a displacement of one meter.
Attojoule [aJ]: An SI-derived unit of energy equal to 10^-18 joules, used for expressing extremely small energy amounts relevant at atomic and molecular scales.
Torque: A measure of rotational force; although sharing the unit newton meter, torque is different conceptually from energy.
