μW/K

microwatt per kelvin

Thermal conductanceexact by definition

The microwatt per kelvin is 10⁻⁶ W/K. Bolometers and transition-edge sensors are designed around a thermal conductance in this range: the weaker the link to the cold bath, the larger the temperature rise per absorbed photon and the more sensitive the detector.
