What Is This Tool?
This tool converts power values from microwatt (µW), a unit representing one millionth of a watt, to picojoule per second (pJ/s), an even smaller power unit equal to 10⁻¹² watts. It supports precise quantification of very low power levels often required in microelectronics, photonics, and ultra-low-power device measurement.
