What does joule per second measure?

Joule per second (J/s) is an SI derived unit that measures power as the rate at which energy is transferred, equivalent to one watt.

In which fields is this conversion commonly applied?

This conversion is mainly used in HVAC, building services, energy systems design, and thermal performance testing.

Why is the Btu (th)/second unit important?

Btu (th)/second quantifies heat transfer rate for thermal energy flow, which is essential for rating and comparing heating and cooling equipment.
