About This Thermal Resistance Converter

Thermal resistance measures how strongly a part, heat path, or insulation layer resists heat flow. This converter separates component thermal resistance from area-specific R-values so unlike dimensions are not mixed.

Use component R units for electronics and heat-sink calculations. Use area R-value units for building insulation and material layers normalized by area.

How to Use It

Choose Component R or Area R-value, enter the value, then select the source and target units within that same dimension.

Units Covered

Component units include K/W, K/kW, °C/W, °C/kW, °F/W, and °F/kW. Area R-value units include m²·K/W, m²·°C/W, and h·ft²·°F/Btu.

Key Features

  • Dimension-Safe Modes: Keeps component thermal resistance separate from area-specific insulation R-values.
  • Engineering Units: Supports watt, kilowatt, Celsius, Kelvin, and Fahrenheit-based thermal resistance units.
  • Construction Values: Converts SI area R-values and common imperial insulation R-values.
  • Practical Focus: Useful for electronics cooling, insulation comparison, and heat-transfer calculations.
