What does 1 nanojoule represent?

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

Why convert between nanojoules and ergs?

Conversion is useful to translate SI energy units into the CGS system, which is common in astrophysics and classical mechanics.

What fields use ergs as a unit?

Ergs are often used in astrophysics for small-scale energy measurements and in classical mechanics calculations when CGS units are applied.
