A low-parametric equation for calculating the SFe viscosity coefficient in liquid, gaseous, and fluid states was derived using previously obtained unambiguous dependence of the “excess” viscosity of liquids and dense gases on the density of internal energy. The equation describes the viscosity of sulfur hexafluoride at the temperatures from 230 K to 650 K and pressures of up to 50 MPa in the limits of experimental error.
