About Watt per metre kelvin
The watt per metre kelvin (W/(m·K)) is the SI unit for thermal conductivity defined by Fourier's law q = -λ∇T. Materials span orders of magnitude: aerogels ≈0.015, glass ≈1.0, stainless steel ≈16, aluminium ≈205, copper ≈385, diamond ≈2200 W/(m·K). Referenced in ISO 22007, EN 12667, and all major international standards. 1 W/(m·K) = 1 W/(m·°C).
About Kilocalorie per metre per hour per degree Celsius
The kcal/(m·h·°C) equals exactly 4186.8/3600 W/(m·K) = 1.163 W/(m·K) (1 kcal(IT) = 4186.8 J). Used in pre-SI continental European engineering literature, older DIN/BS standards, and Soviet-era technical documentation. Brick: ≈0.6; dense concrete: ≈1.3; carbon steel: ≈38 kcal/(m·h·°C). 1 kcal/(m·h·°C) = 1.163 W/(m·K).
