How to Convert Calorie/second/centimeter/°C to Btu/hour/foot/°F

Converting Calorie/second/centimeter/°C (cal/(s·cm·°C)) to Btu/hour/foot/°F (Btu/(h·ft·°F)) is a core calculation in Thermal Conductivity, which measures a material's intrinsic capacity to conduct and transfer heat through microscopic collisions. This calculation navigates the boundary between the International Metric System (SI) and British Imperial / US Customary engineering standards. In contemporary metrology, Imperial units are defined in terms of exact SI standards via international agreements—notably NIST SP 811 and the 1959 International Yard and Pound Agreement. Exactly 1 Calorie/second/centimeter/°C equals 241.908594 Btu/hour/foot/°F, while 1 Btu/(h·ft·°F) equals 0.00413379 cal/(s·cm·°C).

Direct Factor1 cal/(s·cm·°C) = 241.908594 Btu/(h·ft·°F)

Mathematical Conversion Derivation via Coherent SI Base Unit

Under the International System of Quantities (ISQ), dimensional conversion between non-SI units is rigorously resolved by bridging through the coherent SI base unit (watt per meter kelvin (W/(m·K))) without arbitrary rounding:

V_{\text{target}} = V_{\text{source}} \times \left( \frac{k_{\text{source} \to \text{SI}}}{k_{\text{target} \to \text{SI}}} \right)

Universal Dimensional Conversion Law (ISO 80000 / NIST SP 811)

1. Source SI Bridge (k_source):1 cal/(s·cm·°C) = 418.679819 watt per meter kelvin (W/(m·K))

2. Target SI Bridge (k_target):1 Btu/(h·ft·°F) = 1.730736 watt per meter kelvin (W/(m·K))

Step-by-step substitution for Calorie/second/centimeter/°C → Btu/hour/foot/°F:V(Btu/(h·ft·°F)) = V(cal/(s·cm·°C)) × ( 418.679819 / 1.730736 ) = V(cal/(s·cm·°C)) × 241.908594
