What does 1 Btu (IT)/second represent?

It represents the transfer of one International Table British thermal unit of energy every second, a measure of power or heat transfer rate.

Why convert Btu (IT)/second to nanowatts?

Converting allows translating large-scale thermal power values into very small units used in precision electronics and photonics measurements.

Are Btu (IT)/second and nanowatts commonly compared directly?

No, because they apply to vastly different power scales, direct comparison is uncommon.
