Thermal Resistance Converter

What is the thermal resistance converter?

The thermal resistance converter is a collection of calculators for changing one thermal resistance unit into another. Convert thermal resistance units for electronics cooling, heat sinks, HVAC, insulation, thermal design, and heat-flow calculations.

Thermal resistance conversions are used for heat sinks, electronics cooling, HVAC, insulation, thermal design, and heat-flow calculations.

Available thermal resistance units

This category includes the following units:

• Kelvin per Watt (K/W)
• Celsius per Watt (C/W)
• Kelvin per Kilowatt (K/kW)
• Kelvin per Milliwatt (K/mW)
• Fahrenheit Hour per BTU (F h/BTU)

Common thermal resistance use cases

Use this category when the same measurement appears in different unit systems, data sheets, calculators, reports, or regional conventions.

• Convert K/W, C/W, K/kW, K/mW, and F h/BTU for heat-flow and cooling calculations.
• Compare heat sink, electronics, HVAC, insulation, and thermal design data across different unit systems.
• Standardize thermal resistance before estimating temperature rise from power dissipation.

Common thermal resistance conversion mistakes

Most wrong answers come from mixing unit systems, rounding too early, or choosing a unit that looks similar but means something different.

• Do not hide the original thermal resistance unit when copying a result into a report, label, or calculator.
• Do not round intermediate values when the result will be reused in another formula.
• Check whether the source and target units describe the same physical quantity before comparing thermal resistance values.
