How to convert watts per meter kelvin to Btu IT per hour foot Fahrenheit degree
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 W/(m·K), b for the intermediate value in W/(m·K), and y for the result in Btu IT/(h·ft·°F).
Btu IT/(h·ft·°F) = W/(m·K) ÷ 1.730734666371391
Worked examples
10 W/(m·K) ≈ 5.77789316543 Btu IT/(h·ft·°F)
Step 1: (10 × 1) ≈ 10 W/(m·K).
Step 2: 10 ÷ 1.73073466637 ≈ 5.77789316543 Btu IT/(h·ft·°F).20 W/(m·K) ≈ 11.5557863309 Btu IT/(h·ft·°F)
Step 1: (20 × 1) ≈ 20 W/(m·K).
Step 2: 20 ÷ 1.73073466637 ≈ 11.5557863309 Btu IT/(h·ft·°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 Watts per meter kelvin
Watts per meter kelvin (W/(m·K)) measures thermal conductivity under the conventions above. The base value in W/(m·K) is (x × 1), where x is the numerical value in W/(m·K). Factors shown here are rounded for display; calculations use the stored factor.
