How to Convert Kilowatt/Meter-Kelvin to Milliwatt/Meter-Kelvin

To convert from Kilowatt/Meter-Kelvin (kW/(m·K)) to Milliwatt/Meter-Kelvin (mW/(m·K)), multiply the value by 1,000,000.

Formula: mW/(m·K) = kW/(m·K) × 1,000,000

Reverse: kW/(m·K) = mW/(m·K) × 0.000001

Step-by-Step Example

Start with your value in Kilowatt/Meter-Kelvin. For example: 5 kW/(m·K)
Multiply by the conversion factor: 5 x 1,000,000
The result is: 5,000,000 mW/(m·K)

About Kilowatt/Meter-Kelvin

The kilowatt/meter-kelvin (kW/(m·K)) is a unit of thermal conductivity. One kilowatt/meter-kelvin equals 1000 base units. UnitConvertLab converts it against every other thermal conductivity unit using this exact definition, so results are reproducible to full double precision rather than rounded lookup tables.

Common uses: thermal conductivity calculations, engineering and science, education.

About Milliwatt/Meter-Kelvin

The milliwatt/meter-kelvin (mW/(m·K)) is a unit of thermal conductivity. One milliwatt/meter-kelvin equals 0.001 base units. UnitConvertLab converts it against every other thermal conductivity unit using this exact definition, so results are reproducible to full double precision rather than rounded lookup tables.
