How to Convert Kilowatt/square meter kelvin to CHU/hour/square foot/°C

Converting Kilowatt/square meter kelvin (kW/(m²·K)) to CHU/hour/square foot/°C (CHU/(h·ft²·°C)) is a core calculation in Heat Transfer Coefficient, which quantifies the proportionality constant between the heat flux and the thermodynamic driving temperature difference. 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 Kilowatt/square meter kelvin equals 176.11 CHU/hour/square foot/°C, while 1 CHU/(h·ft²·°C) equals 0.00567827 kW/(m²·K).

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 square meter kelvin (W/(m²·K))) without arbitrary rounding:

Vtarget=Vsource×(ksource→SIktarget→SI)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 (ksource):1 kW/(m²·K) = 1000 watt per square meter kelvin (W/(m²·K))
2. Target SI Bridge (ktarget):1 CHU/(h·ft²·°C) = 5.678269 watt per square meter kelvin (W/(m²·K))
Step-by-step substitution for Kilowatt/square meter kelvin → CHU/hour/square foot/°C:V(CHU/(h·ft²·°C)) = V(kW/(m²·K)) × ( 1000 / 5.678269 ) = V(kW/(m²·K)) × 176.11
Mathematical FormulaValue in CHU/hour/square foot/°C = Value in Kilowatt/square meter kelvin × 176.11Direct computational formula applied for standard conversion.
Worked Example

For an engineering input of 15 kW/(m²·K), applying the conversion factor yields exactly 2641.65 CHU/(h·ft²·°C). At larger operational scale, 10000 Kilowatt/square meter kelvin corresponds to 1761100 CHU/(h·ft²·°C).

Inverse check: 1 CHU/(h·ft²·°C) = 0.00567827 kW/(m²·K).
