How to convert kilowatts per square meter kelvin to Btu IT per hour square foot Fahrenheit degree
The coefficient relates heat flux to a temperature difference. It is not thermal conductivity; geometry and flow conditions matter when determining the original coefficient.
Use x for the value in kW/(m²·K), b for the intermediate value in W/(m²·K), and y for the result in Btu IT/(h·ft²·°F).
Btu IT/(h·ft²·°F) = kW/(m²·K) × 1000 ÷ 5.678263341113487
Worked examples
10 kW/(m²·K) ≈ 1761.10183682 Btu IT/(h·ft²·°F)
Step 1: (10 × 1000) ≈ 10000 W/(m²·K).
Step 2: 10000 ÷ 5.67826334111 ≈ 1761.10183682 Btu IT/(h·ft²·°F).20 kW/(m²·K) ≈ 3522.20367365 Btu IT/(h·ft²·°F)
Step 1: (20 × 1000) ≈ 20000 W/(m²·K).
Step 2: 20000 ÷ 5.67826334111 ≈ 3522.20367365 Btu IT/(h·ft²·°F).
Results are rounded to 12 significant digits. Converting units does not increase the precision of the original measurement. Very large or small values outside JavaScript’s finite numeric range are rejected.
About Kilowatts per square meter kelvin
Kilowatts per square meter kelvin (kW/(m²·K)) measures heat transfer coefficient under the conventions above. The base value in W/(m²·K) is (x × 1000), where x is the numerical value in kW/(m²·K). Factors shown here are rounded for display; calculations use the stored factor.
