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

Converting CHU/hour/square foot/°C (CHU/(h·ft²·°C)) to Kilowatt/square meter kelvin (kW/(m²·K)) 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 CHU/hour/square foot/°C equals 0.00567827 Kilowatt/square meter kelvin, while 1 kW/(m²·K) equals 176.11 CHU/(h·ft²·°C).

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 CHU/(h·ft²·°C) = 5.678269 watt per square meter kelvin (W/(m²·K))
2. Target SI Bridge (ktarget):1 kW/(m²·K) = 1000 watt per square meter kelvin (W/(m²·K))
Step-by-step substitution for CHU/hour/square foot/°C → Kilowatt/square meter kelvin:V(kW/(m²·K)) = V(CHU/(h·ft²·°C)) × ( 5.678269 / 1000 ) = V(CHU/(h·ft²·°C)) × 0.00567827

Worked Example

To convert 120 CHU/hour/square foot/°C (CHU/(h·ft²·°C)) to Kilowatt/square meter kelvin (kW/(m²·K)): multiply 120 by 0.00567827 to get 0.681392 kW/(m²·K). At an industrial engineering scale, 2500 CHU/(h·ft²·°C) converts to 14.195673 kW/(m²·K).
