How to convert Btu IT per hour foot Fahrenheit degree to milliwatts per meter kelvin
Thermal conductivity is a material property at specified conditions. It differs from conductance (W/K) and heat-transfer coefficient (W/m²/K).
Use x for the value in Btu IT/(h·ft·°F), b for the intermediate value in W/(m·K), and y for the result in mW/(m·K).
mW/(m·K) = Btu IT/(h·ft·°F) × 1.730734666371391 ÷ 0.001
Worked examples
10 Btu IT/(h·ft·°F) ≈ 17307.3466637 mW/(m·K)
Step 1: (10 × 1.73073466637) ≈ 17.3073466637 W/(m·K).
Step 2: 17.3073466637 ÷ 0.001 ≈ 17307.3466637 mW/(m·K).20 Btu IT/(h·ft·°F) ≈ 34614.6933274 mW/(m·K)
Step 1: (20 × 1.73073466637) ≈ 34.6146933274 W/(m·K).
Step 2: 34.6146933274 ÷ 0.001 ≈ 34614.6933274 mW/(m·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 foot Fahrenheit degree
Btu IT per hour foot Fahrenheit degree (Btu IT/(h·ft·°F)) measures thermal conductivity under the conventions above. The base value in W/(m·K) is (x × 1.73073466637), where x is the numerical value in Btu IT/(h·ft·°F). Factors shown here are rounded for display; calculations use the stored factor.
About Milliwatts per meter kelvin
