The absolute viscosity of some common liquids at temperatures between –25 °C and 100 °C is given in this table. Values were derived by fitting experimental data to suitable expressions for the temperature dependence. All values are given in units of millipascal seconds (mPa s); this unit is identical to centipoise (cp).
Viscosity values correspond to a nominal pressure of 1 atmosphere. However, if a value is given at a temperature above the normal boiling point, the applicable pressure is understood to be the vapor pressure of the liquid at that temperature. A few values are given at a temperature slightly below the normal freezing point; these refer to the supercooled liquid.
The accuracy ranges from 1% in the best cases to 5 to 10% in the worst cases. Additional significant figures are included in the table to facilitate interpolation. Column definitions for the table are as follows.
