μK
microkelvin (difference)
Temperature differenceexact by definition
A microkelvin difference is 10⁻⁶ K. It is the stability specification of a metrology-grade fixed-point cell and of the temperature control on an optical cavity, where a microkelvin drift is enough to move a laser frequency measurably.
