What does one watt represent in power measurement?

One watt (W) is the SI derived unit of power, representing one joule of energy transferred or converted per second.

Why convert watts to Btu (th)/hour?

Converting watts to Btu (th)/hour helps evaluate heating and cooling rates in HVAC and thermal systems where Btu (th)/hour is the standard unit.

Can this conversion be used for dynamic thermal processes?

No, this conversion primarily applies under steady-state conditions, and dynamic processes may need more detailed evaluations.
