This paper reports new measurements of the thermal conductivity of sulfur hexafluoride at the nominal temperature of 27.5&C as a function of density in the range up to 200 kg m−3. The measurements were performed in a transient, hot wire instrument. When combined with earlier measurements of the viscosity of the gas, they allow us to calculate the rather large contribution stemming from
