Kilocalorie per centimetre per hour per degree Celsius (kcal/(cm·h·°C))
Watt per metre kelvin (W/(m·K))

Conversion Formula

W/(m·K) = kcal/(cm·h·°C) × 116.3

About Kilocalorie per centimetre per hour per degree Celsius

The kcal/(cm·h·°C) equals exactly 4186.8/36 W/(m·K) = 116.3 W/(m·K) (1 kcal(IT) = 4186.8 J; 1 h = 3600 s; 1 cm = 0.01 m). Used in older CGS-metric European and Soviet literature for metallic heat transfer. Steel: ≈0.137; copper: ≈3.31 kcal/(cm·h·°C). 1 kcal/(cm·h·°C) = 116.3 W/(m·K) = 100 × kcal/(m·h·°C).

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).
