The cgs physical unit for **dynamic viscosity**, the poise (P), is also named after Jean Poiseuille. It is more commonly expressed, particularly in ASTM standards, as centipoise (cP) since the latter is equal to the SI multiple millipascal seconds (mPa·s).

For example, water at 20 °C has a **dynamic viscosity** of 1.002 mPa·s = 1.002 cP.
