What does nanojoule per second measure?

Nanojoule per second (nJ/s) measures a very small power level equal to one nanowatt, representing energy transfer or conversion at a rate of 10⁻⁹ joules per second.

Where is Btu (IT) per second commonly used?

Btu (IT)/second is typically used to specify heat output in boilers, furnaces, and HVAC systems, as well as in engineering calculations involving heat transfer.

Why do conversions between nJ/s and Btu (IT)/s yield very small numbers?

Because nanojoule per second represents much smaller power levels compared to British thermal units per second, conversion results are very small fractional values.
