Frequently Asked Questions
-
What does kelvin per watt (K/W) measure?
-
Kelvin per watt quantifies thermal resistance by representing the temperature difference across a material or device per unit of steady heat flow.
-
Why convert from K/W to degree Fahrenheit second/Btu (IT)?
-
Converting facilitates compatibility in thermal modeling and design where temperature and power units from different measurement systems are used.
-
Is this conversion suitable for transient thermal analysis?
-
No, the conversion applies to steady-state thermal resistance; transient conditions may need additional parameters beyond this unit conversion.
