About Microkelvin per watt

The microkelvin per watt (μK/W) equals exactly 10⁻⁶ K/W. Used in ultra-precision cryogenic and nanotechnology research to characterise thermal contact resistance of atomically bonded interfaces, van der Waals heterostructures, and superconducting qubit heat links at millikelvin temperatures. Also quoted for on-chip thermal connections in quantum processor prototypes. 1 μK/W = 10⁻⁶ K/W.

About Second-degree Fahrenheit per BTU

The second-degree Fahrenheit per BTU (s·°F/BTU) equals (5/9)/1055.05585262 K/W ≈ 5.265 × 10⁻⁴ K/W. Used in US aerospace and nuclear engineering where thermal transient analyses express power as BTU/s and temperature in °F, e.g. rocket engine heat rejection and reactor coolant loop calculations. 1 s·°F/BTU ≈ 5.265 × 10⁻⁴ K/W.
