WebNow from what I researched to convert w/mk to w/m²k you need the formula R=l/λ. (l=material thickness). So the R value is basically Ug. But if R=l/λ doesn't that mean that the higher the R value the better material will be in terms of heat conductivity??? Since λ Value should be the lower the better???
