| In [[heat transfer]], the '''[[thermal conductivity]]''' of a substance, k, is an [[intensive property]] that indicates its ability to conduct [[heat]].
| |
|
| |
|
| [[Thermal conductivity]] is often measured with [[Laser Flash Analysis|laser flash analysis]]. Alternative [[Thermal conductivity measurement|measurements]] are also established.

| Mixtures may have variable thermal conductivities due to composition.

| Note that this table shows thermal conductivity in units of watts per meter per Kelvin (W·m<sup>−1</sup>·K<sup>−1</sup>). This is the current metric unit of measurement. Prior to this, however, thermal conductivity was measured in terms of [[BTU]]s per foot per hour per degree Fahrenheit. A value for the former can be computed from the latter by multiplying by 1.728.<ref name="Wright2010">{{citation|author=Roger N.
