Thermal Resistance Units Converter
Additional information
Thermal resistance, often denoted by the symbol (R), is a measure of how much a material or component resists the flow of heat through it. It quantifies the difficulty with which heat can pass through a material or an object.
The thermal resistance of a material or component depends on its physical properties, such as thermal conductivity, thickness, and area. It is a crucial parameter in many engineering applications, particularly in designing and evaluating heat transfer systems, thermal insulation, electronic cooling, and managing temperature gradients in various devices and structures.
Mathematically, thermal resistance can be found using the following formula:
Where:
- R is the thermal resistance
- ΔT is the temperature difference across the material
- Q is the heat flow rate through the material
The standard unit for thermal resistance in the International System of Units (SI) is kelvin per watt (K/W).
