What does joule per hour measure?

It measures power as the amount of energy transferred or converted per hour, useful for very low continuous power levels over long durations.

Why convert joule/hour to picojoule/second?

The conversion allows expressing low power measured over hours into much smaller instantaneous power units relevant for micro and nanotechnology.

Can this conversion be used for dynamic power measurements?

No; the conversion assumes steady power over the hour, so it may not accurately reflect dynamic or rapidly changing power profiles.
