What does an attowatt measure?

An attowatt quantifies power at an extremely small scale, equal to 10^-18 watts, commonly used in scientific fields requiring detection of minimal energy transfer.

What is a Btu (th)/second used for?

It measures the rate at which thermal energy is transferred, particularly useful for heating, cooling, and energy conversion system evaluations.

Why convert attowatts to Btu (th)/second?

Converting from attowatts to Btu (th)/second helps relate ultra-low power scientific data to practical thermal energy flow in engineering and HVAC contexts.
