A nanojoule is an SI-derived energy unit equal to one billionth of a joule, commonly used to measure very small energy amounts.

How is a joule defined?

A joule is the SI derived unit of energy, defined as the energy transferred when a force of one newton moves an object one meter; it also equals one watt-second.

Why convert nanojoules to joules?

Converting nanojoules to joules helps integrate tiny energy measurements into broader physical calculations using the standard SI unit.
