To calculate the U-Value (U):
\[ U = \frac{1}{R} \]
Where:
W/m²K, or watts per square meter per degree Kelvin, is a unit of measurement used in physics to describe the rate of heat flow. The U-value, also known as the overall heat transfer coefficient, is a measure of the rate of heat loss through a structure (such as a wall, floor, or roof). It is expressed in W/m²K and the lower the U-value, the better the material is at insulating. Therefore, converting W/m²K to a U-value essentially involves understanding the insulating properties of a material.
Let's assume the following value:
Using the formula:
\[ U = \frac{1}{5} = 0.20000 \]
The U-Value is 0.20000 W/m²K.
Let's assume the following value:
Using the formula:
\[ U = \frac{1}{3} = 0.33333 \]
The U-Value is 0.33333 W/m²K.
