What the thermal resistance converter solves
Use the thermal resistance converter for insulation R-values, building science examples, and heat-transfer layer comparisons.
Formula
How to use it
- Enter the value to convert.
- Choose the source unit and target unit.
- Use the shown conversion rate to check the direction.
How to read the answer
The converted value uses m^2 K/W as the shared bridge unit so every pair in this unit family stays consistent.
Common mistakes and edge cases
- This page converts area-normalized thermal resistance, not point thermal resistance in K/W.
- US R-value uses h ft^2 F/BTU; RSI uses m^2 K/W.
- An assembly R-value may include films, gaps, studs, or layers that are not captured by a single material value.

Frequently asked questions
What formula does the thermal resistance converter use?+
It converts the source value into a base unit, then divides by the target unit factor.
Why is the conversion rate shown?+
The rate makes it easier to verify that the calculator used the direction you intended.
