What does 1 watt [W] represent in picojoule/second [pJ/s]?

1 watt is equivalent to 1,000,000,000,000 picojoule/second, since 1 pJ/s equals 10⁻¹² watts.

Why would I convert watts to picojoule/second?

Converting allows expressing very small continuous power levels for applications like microelectronics and photonics where sensitivity is crucial.

Is this conversion suitable for all power ranges?

No, it is mainly suitable for very low power measurements; using it for large power values leads to excessively large unit numbers.
