What does one watt represent in terms of power?

One watt is the SI derived unit of power equal to one joule of energy transferred or converted per second.

When should I use nanojoule per second instead of watt?

Nanojoule per second is best used to represent very small continuous power levels such as in ultra-low-power sensors, microelectronics, and photonics.

Why do conversion results from watt to nanojoule/second produce such large numbers?

Because one watt equals one billion nanojoules per second, converting leads to large numerical values reflecting tiny units.
