How to convert watts per meter kelvin 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 W/(m·K), b for the intermediate value in W/(m·K), and y for the result in mW/(m·K).
mW/(m·K) = W/(m·K) ÷ 0.001
Worked examples
10 W/(m·K) ≈ 10000 mW/(m·K)
Step 1: (10 × 1) ≈ 10 W/(m·K).
Step 2: 10 ÷ 0.001 ≈ 10000 mW/(m·K).20 W/(m·K) ≈ 20000 mW/(m·K)
Step 1: (20 × 1) ≈ 20 W/(m·K).
Step 2: 20 ÷ 0.001 ≈ 20000 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 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.
About Milliwatts per meter kelvin
Milliwatts per meter kelvin (mW/(m·K)) measures thermal conductivity under the conventions above. The base value in W/(m·K) is (x × 0.001), where x is the numerical value in mW/(m·K). Factors shown here are rounded for display; calculations use the stored factor.
