Frequently Asked Questions
-
What is the relationship between nanojoule and newton meter?
-
One nanojoule is equal to 1×10⁻⁹ newton meters, indicating their direct dimensional relationship as units of energy.
-
Can newton meters represent torque as well as energy?
-
Yes, the newton meter is used both as a unit of energy and torque, but torque and energy are different physical quantities despite sharing units.
-
Why convert nanojoules to newton meters?
-
Converting nanojoules to newton meters helps express very small energy values in terms of mechanical work or torque equivalents for physics and engineering analyses.
Key Terminology
-
Nanojoule [nJ]
-
An SI-derived unit of energy equal to one billionth of a joule, used for quantifying very small energy amounts.
-
Newton meter [N*m]
-
A unit of work or energy equal to the work done by a force of one newton moving an object one meter; also used to express torque.
-
Torque
-
A rotational force represented in newton meters but conceptually distinct from energy.
