A method was proposed for predicting the viscosity of organic liquids which is based on known saturated vapour pressures and the chemical structure. For 199 compounds (4 144 measurements), the method gives the mean relative deviation of 3.35% and the maximum deviation of 59.0%. A lower mean value of the relative deviation than 2% was obtained for 44.3% compounds, 76% compounds possess a lower deviation than 5%.
