Limitations
-
Nanojoule/second is an SI-based unit, while erg/second belongs to the CGS system, reflecting different measurement bases.
-
Converting may lead to floating-point precision challenges due to very small quantities.
-
Erg per second is less common in modern engineering contexts.
Frequently Asked Questions
-
What does 1 nanojoule per second represent?
-
1 nanojoule per second equals one nanowatt, signifying 10⁻⁹ joules transferred or converted each second.
