What is a microwatt used to measure?

A microwatt measures very small power levels, often in electrical, optical, or biomedical systems, such as power consumption of ultra-low-power sensors and output from photodiodes.

Why convert microwatts to Btu (IT)/second?

Converting microwatts to Btu (IT)/second helps relate small electrical or optical power to heat transfer rates, allowing comparisons with thermal systems or HVAC components.

Are microwatts and Btu (IT)/second units directly comparable?

While both measure power, microwatts quantify very low electrical power, and Btu (IT)/second is a larger unit used for heat transfer, so values in Btu/s are often very small after conversion.
