About Kelvin per Watt (K/W)
The SI unit of absolute thermal resistance, representing the temperature difference in kelvins across a structure when 1 watt of heat flows through it.
History: Introduced as the thermal analogue of electrical resistance (Ohm’s law analogue: ΔT = P × R_th).
Common Uses: Semiconductor heatsink ratings, junction-to-ambient thermal resistance, electronics cooling design.
About Fahrenheit Hour per IT BTU (°F·h/Btu_IT)
The imperial unit of absolute thermal resistance, derived from 1 °F interval (5/9 K), 1 hour (3600 s), and 1 IT BTU (1055.05585262 J).
History: Standard unit in US architectural engineering and building thermal performance.
Common Uses: Building component absolute thermal resistance, HVAC architectural load sizing.
