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

Converting Calorie/second/centimeter/°C (cal/(s·cm·°C)) to Btu inch/hour/sq. foot/°F (Btu·in/(h·ft²·°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 2902.903963 Btu inch/hour/sq. foot/°F, while 1 Btu·in/(h·ft²·°F) equals 0.000344483 cal/(s·cm·°C).

Direct Factor1 cal/(s·cm·°C) = 2902.903963 Btu·in/(h·ft²·°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·in/(h·ft²·°F) = 0.144228 watt per meter kelvin (W/(m·K))

Step-by-step substitution for Calorie/second/centimeter/°C → Btu inch/hour/sq. foot/°F:V(Btu·in/(h·ft²·°F)) = V(cal/(s·cm·°C)) × ( 418.679819 / 0.144228 ) = V(cal/(s·cm·°C)) × 2902.903963

Worked Example

To convert 2.5 Calorie/second/centimeter/°C (cal/(s·cm·°C)) to Btu inch/hour/sq. foot/°F (Btu·in/(h·ft²·°F)): multiply 2.5 by 2902.903963 to get 7257.259908 Btu·in/(h·ft²·°F). At an industrial engineering scale, 10000 cal/(s·cm·°C) converts to 2.902904 × 10⁷ Btu·in/(h·ft²·°F).

Inverse check: 1 Btu·in/(h·ft²·°F) = 0.000344483 cal/(s·cm·°C).
