How to calculate thermal conductance
Thermal conductance measures how easily heat flows through a material or system per unit temperature difference — calculated by dividing heat transfer rate by temperature difference.
How the calculation works
Thermal conductance = Heat transfer rate ÷ Temperature difference.
Example
500 watts of heat transfer across a 25°C temperature difference: 500÷25 = 20 W/°C.

Pro Tips for Thermal Conductance
- Higher thermal conductance means heat flows more easily through the material or assembly — the inverse relationship to thermal resistance (R-value).
- Keep heat transfer rate and temperature difference in consistent units for a meaningful, comparable conductance figure.
Common Thermal Conductance Mistakes to Avoid
- Confusing thermal conductance (higher is more heat flow) with thermal resistance/R-value (higher means less heat flow), which are inversely related concepts.
