WebThe cgs physical unit for dynamic viscosity is the poise (P). The more common unit is centipoise (cP). The more common unit is centipoise (cP). Water at 20°C has a viscosity of 0.001002 Pa·s or 1.0020 cP. Observed values of viscosity vary over several orders of magnitude, even for common substances (see the order of magnitude table below). For instance, a 70% sucrose (sugar) solution has a viscosity over 400 times that of water, and 26000 times that of air. More dramatically, pitch has been estimated to have a viscosity 230 billion times that of water.
