UnitConThermal Resistance
Thermal resistance measures how strongly a material or system resists heat flow. It appears in building insulation ratings, electronics cooling, and thermal design calculations. This converter helps compare SI and US insulation-related units clearly. It is useful for homeowners, HVAC professionals, and engineers.

Frequently asked questions
R-value is a practical expression of thermal resistance used in US building construction. Higher R-values indicate better resistance to heat flow.
The best R-value depends on climate zone, building code, and roof design. Local guidance is more reliable than one universal number.
In electronics, thermal resistance describes how easily heat moves from a component to its surroundings. Lower thermal resistance usually means better cooling performance.
