K-Value, U-Value, R-Value, C-Value - Insulation …
Equation 2: R-value = 1 / C-value. If the C-value is 0.5, then the R-value is 2.0. One can calculate it from the equation for C-value in Equation 1 above: Equation 3: R-value = thickness / K-value. Thus, if the thickness is 1 inch, and the K-value is 0.25, then the R-value is 1 divided by 0.25, or 4 (leaving off the units for brevity). U-value
