What does one microjoule per second represent?

It is a unit of power representing the transfer of one microjoule of energy every second, corresponding to 10⁻⁶ watts.

In what industries is this conversion useful?

It is commonly used in microelectronics, photonics, energy harvesting research, HVAC design, and thermal engineering.

Why is the conversion often theoretical?

Because microjoule/second units measure extremely small power compared to Btu (th)/second, conversions mostly serve to scale data rather than direct practical measurement.
