What does Btu (th)/hour measure?

Btu (th)/hour measures power using thermochemical British thermal units transferred per hour, commonly used for heating or cooling rates.

Why convert to microjoule/second?

Microjoule/second expresses very small continuous power levels used in electronics, photonics, and low-power sensor systems.

Can I use this conversion for very large heating loads?

Yes, but the resulting microjoule/second values become extremely large and may require careful numerical handling.
