What does femtojoule/second measure?

It measures extremely small power levels, representing energy transfer rates on the scale of 10^-15 watts.

Why convert femtojoule/second to Btu (IT)/hour?

This conversion enables comparing very small power measurements used in physics with conventional heat transfer units in HVAC and heating systems.

Can I use converted values directly for HVAC equipment sizing?

Due to their small magnitude, converted values may require scaling before practical use in HVAC design.
