How to convert milliwatts per meter kelvin to watts 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 mW/(m·K), b for the intermediate value in W/(m·K), and y for the result in W/(m·K).

W/(m·K) = mW/(m·K) × 0.001

Worked examples

  • 10 mW/(m·K) ≈ 0.01 W/(m·K)

    Step 1: (10 × 0.001) ≈ 0.01 W/(m·K).
    Step 2: 0.01 ÷ 1 ≈ 0.01 W/(m·K).

  • 20 mW/(m·K) ≈ 0.02 W/(m·K)

    Step 1: (20 × 0.001) ≈ 0.02 W/(m·K).
    Step 2: 0.02 ÷ 1 ≈ 0.02 W/(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 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.
