What does Btu (IT)/second measure?

It represents the rate of heat transfer or energy conversion based on the International Table British thermal unit per second.

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

This is done to express large-scale heat transfer rates in extremely fine, nano-scale power units relevant to experimental physics and nanotechnology.

Can femtojoule/second be used for everyday power calculations?

No, because femtojoule/second is extremely small, it is impractical for common heat or power engineering tasks.
