What industries commonly use Btu (th)/hour?

Btu (th)/hour is frequently used in HVAC design, building heating and cooling load calculations, and specifying heat output for water heaters and boilers.

Why convert Btu (th)/hour to femtojoule/second?

Converting to femtojoule/second helps translate conventional thermal power measurements into extremely small energy scales relevant in nanoelectronics and quantum experiments.

Are the measurement contexts for these units the same?

No, Btu (th)/hour is oriented toward macroscopic heat transfer, while femtojoule/second is intended for atomic and subatomic level phenomena, so their typical use cases do not overlap highly.
