What does one Btu (IT)/second represent in power?

One Btu (IT)/second signifies the power corresponding to one British thermal unit transferred per second, approximately equal to 1,055.05585262 watts.

When would I need to convert Btu (IT)/second to femtowatt?

You might convert these units when analyzing power levels that span from large heat transfer rates to extremely small signals in sensitive or nanoscale systems.

Are femtowatt measurements suitable for typical HVAC applications?

No, femtowatts measure extremely low power levels and are more appropriate for nanoscale or ultra-sensitive electronic devices rather than standard HVAC systems.
