What is a picowatt (pW)?

A picowatt is an SI-derived unit of power equal to one trillionth of a watt, used for measuring very small power levels in sensitive instruments and experiments.

What does kilocalorie (th)/second represent?

Kilocalorie (th)/second measures the rate of heat transfer based on thermochemical calories, equivalent to 4184 watts, commonly used to specify thermal power and heat flow rates.

Why convert picowatt to kilocalorie (th)/second?

Converting picowatts to kilocalorie (th)/second helps relate tiny electrical power measurements to thermal energy transfer, useful in scientific and thermal engineering contexts.
