How to convert Btu IT per hour square foot Fahrenheit degree to kilowatts per square meter kelvin
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 Btu IT/(h·ft²·°F), b for the intermediate value in W/(m²·K), and y for the result in kW/(m²·K).
kW/(m²·K) = Btu IT/(h·ft²·°F) × 5.678263341113487 ÷ 1000
Worked examples
10 Btu IT/(h·ft²·°F) ≈ 0.0567826334111 kW/(m²·K)
Step 1: (10 × 5.67826334111) ≈ 56.7826334111 W/(m²·K).
Step 2: 56.7826334111 ÷ 1000 ≈ 0.0567826334111 kW/(m²·K).20 Btu IT/(h·ft²·°F) ≈ 0.113565266822 kW/(m²·K)
Step 1: (20 × 5.67826334111) ≈ 113.565266822 W/(m²·K).
Step 2: 113.565266822 ÷ 1000 ≈ 0.113565266822 kW/(m²·K).
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 Btu IT per hour square foot Fahrenheit degree
