How to convert thermal conductivity
1 × 1 ÷ 0.001 = 1000 Milliwatts per metre-kelvin.
Multiply your measurement by the factor for the input unit, then divide by the factor for the output unit. Every factor below is expressed in watts per metre-kelvin per one unit. For example, 1 Watts per metre-kelvin equals 1000 Milliwatts per metre-kelvin.

Accuracy and scope
The calculator uses fixed measurement relationships and SI decimal prefixes, including the 2022 ronto, quecto, ronna and quetta prefixes. Conventional units are identified separately when available. Results are rounded for display to 12 significant digits; very large and small values may lose precision in ordinary browser floating-point arithmetic. This converter changes units of the same physical quantity and does not change the measured quantity itself.
