The viscosity of water at a temperature of 20 degrees Celsius is approximately 0.01 poise or 10-3 Pa. s (Pascal seconds). Viscosity is a measure of the resistance of a fluid to deformation at a given rate.

The viscosity of air depends mostly on the temperature. At 15 °C, the viscosity of air is 1.81 *10-5 kg/(m*s) , 18.1 μPa.s or 1.81 *10-5 Pa.s .
