What is a picowatt and where is it commonly used?

A picowatt is a unit of power equal to one trillionth of a watt, often used in sensitive measurement instruments and ultra-low-power electronics.

Why convert picowatts to Btu (th)/second?

This conversion helps translate extremely small electrical power readings into thermal power units for heat transfer and HVAC system analysis.

Are picowatt to Btu (th)/second conversions practical for typical heating systems?

Due to the very small magnitude, these conversions may have limited relevance for typical heating or cooling system scales.
