What is a picowatt used to measure?

A picowatt measures extremely small power levels such as noise or signal power in sensitive detectors and ultra-low-power electronic devices.

Why convert picowatts to Btu (th)/hour?

Converting picowatts to Btu (th)/hour allows for interpreting tiny power levels in the context of heating or cooling loads relevant to thermal management.

Are there any limitations to this conversion?

Yes, the conversion yields very small decimal values, and it assumes the use of thermochemical Btu units, limiting its application with other Btu definitions.
