Convert Kilocalorie per metre per hour per degree Celsius to Microwatt per metre kelvin
Convert Kilocalorie per metre per hour per degree Celsius (kcal/(m·h·°C)) to Microwatt per metre kelvin (µW/(m·K)) instantly and accurately.
Conversion Formula
µW/(m·K) = kcal/(m·h·°C) × 1163000
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).
About Microwatt per metre kelvin
The microwatt per metre kelvin (µW/(m·K)) equals exactly 10⁻⁶ W/(m·K). Used for near-vacuum conditions and evacuated superinsulation systems where the effective thermal conductivity falls well below the mW/(m·K) range. Evacuated multi-layer insulation (MLI) at high vacuum can reach 0.001-10 µW/(m·K) effective conductivity. Completes the SI prefix chain below mW/(m·K). 1 µW/(m·K) = 10⁻⁶ W/(m·K) = 10⁻³ mW/(m·K).
