What does Btu (th)/minute represent?

It is a unit of power representing the rate of heat transfer as one thermochemical British thermal unit per minute, commonly used in heating or cooling capacity.

When should I use femtowatt units?

Femtowatt units are ideal for expressing extremely low power levels, such as those in nanoscale electronics, ultra-sensitive photodetectors, or cryogenic sensors.

Are there any challenges converting between these units?

Yes, because Btu (th)/minute and femtowatt differ hugely in magnitude, the conversion yields very large numbers that may challenge software precision and practical interpretation.
