Why is the microwatt to Btu (th)/second value so small?

Because one microwatt represents an extremely small amount of power, the equivalent heat transfer rate in Btu (th)/second is also very small.

What are typical applications for converting microwatts to Btu (th)/second?

Common uses include thermal management of low-power electronic devices, HVAC equipment capacity analysis, and energy system performance evaluations.

Are there any challenges when using this converter?

Yes, the tiny conversion factor means precision measurement and understanding of differences in power domains are necessary for accurate interpretation.
