What does one Btu (th)/second represent?

It is a unit of power that measures the rate of thermal energy transfer equal to one thermochemical British thermal unit delivered every second.

Why convert Btu (th)/second to nanowatt?

Converting allows expressing large thermal power values into extremely small power units useful in low-power electronics and precise scientific measurements.

Can nanowatt units be used for regular HVAC power ratings?

Generally, nanowatts are impractical for typical HVAC power values because of the large scale difference and are used mainly for highly specialized comparisons.
