What is a nanowatt (nW)?

A nanowatt is an SI unit of power equal to 10⁻⁹ watts, used to measure very low power levels in applications like microelectronics and photonics.

What does terajoule per second (TJ/s) represent?

A terajoule per second is a large power unit equal to one terajoule (10¹² joules) transferred each second, equivalent to 10¹² watts or one terawatt.

Why convert nanowatts to terajoules per second?

Converting between these units helps compare power from ultra-low-level devices to massive power grid outputs, useful in energy planning and engineering modeling.
