How thermal resistance conversion works
Thermal resistance relates a temperature difference to the heat-transfer rate through a system. Values are normalized to Kelvin/watt before conversion to the requested output unit.
Values are converted to kelvin/watt first, then from that reference into the requested unit. Keeping a single documented reference reduces inconsistent pair-by-pair constants.

Questions
Thermal Resistance FAQ
What is the reference unit for thermal resistance conversions?
ConvertWin uses kelvin/watt (K/W) as the internal reference for this category, then converts to the selected output unit.
How accurate is this thermal resistance converter?
SI relationships follow the cited reference. Conventional and domain-specific factors use the established ConvertWin factor inventory; verify safety-critical work against the governing standard.
