What does joule per second (J/s) represent?

Joule per second is the SI derived unit of power measuring the rate of energy transfer or expenditure; it is exactly equal to one watt.

Where is Btu (th)/hour commonly used?

Btu (th)/hour is mainly used for quantifying heating or cooling rates in HVAC systems, boilers, heat exchangers, and refrigeration applications.

Can this tool convert other power units?

No, this tool specifically converts power from joule per second to Btu (th)/hour and does not support other unit conversions.
