This table gives the thermal conductivity λ of 277 liquids at temperatures between –25 °C and 100 °C. Values refer to nominal atmospheric pressure; however, when an entry is given for a temperature above the normal boiling point of the liquid, the pressure is understood to be the saturation vapor pressure at that temperature. Additional data at pressures above saturation can be found in most of the cited references. Values given to three decimal places (i.e., to 0.001 W m-1 K-1) have an uncertainty of 2% to 5%. Values given to 0.0001 W m-1 K-1 are accurate to 1% or better. Entries reported with two digits should be considered as predictions with uncertainties in the range of 10-25%.
Column definitions for the table are as follows.
