What does one nanowatt represent?

A nanowatt is an SI-derived unit of power equal to 10⁻⁹ watts, used to measure extremely low power levels.

Where is Btu (IT)/second commonly used?

Btu (IT)/second is used to specify heat output in boilers, furnaces, HVAC systems, and energy calculations involving heat transfer.

Why convert nanowatts to Btu (IT)/second?

This conversion helps express very small electrical power levels in thermal power units, enabling comparisons and calculations across different energy domains.
