The W/m²K to U Value Calculator is a practical tool designed to facilitate the conversion between thermal conductivity and U-value. Thermal conductivity, measured in watts per square meter per Kelvin (W/m²K), represents the ability of a material to conduct heat. On the other hand, the U-value, also expressed in units of W/m²K, denotes the overall heat transfer coefficient of a structure or building component. The calculator simplifies this conversion process, allowing users to quickly obtain the U-value from the given thermal conductivity value.
Formula of W/m²K to U Value Calculator
The formula used in the W/m²K to U Value Calculator is straightforward:
U = 1 / (W/m²K)
Where:
- U is the U-value in units of W/m²K.
Table of General Terms

This table provides a quick reference for users, enhancing their understanding of the terms associated with thermal conductivity and U-value.
Example of W/m²K to U Value Calculator
Let’s consider an example to illustrate the usage of the W/m²K to U Value Calculator:
Suppose we have a material with a thermal conductivity of 0.05 W/m²K. Using the calculator, we can determine the corresponding U-value as follows:
U = 1 / 0.05 = 20 W/m²K
So, the U-value of the material is 20 W/m²K.
Most Common FAQs
Thermal conductivity refers to the ability of a material to conduct heat. It is measured in watts per square meter per Kelvin (W/m²K).
The U-value, also known as the overall heat transfer coefficient, is crucial in building design as it indicates the rate of heat transfer through a material or structure. A lower U-value signifies better insulation and energy efficiency.
A lower U-value indicates better insulation properties, meaning the material is more effective at resisting heat transfer. Therefore, when selecting materials for building construction or insulation, aim for lower U-values to improve energy efficiency.
